The Creonic AWGN Channel IP implements an AWGN noise generator capable of working up to a maximum of 512 symbols in parallel. The IP was developed with the aim of allowing the performance evaluation of a digital communication system in the presence of Additive White Noise and with a major emphasis on dealing with low bit-error-rates. Unlike a software-based AWGN generator, which might take several hours and even days for the stated purpose, a hardware-based AWGN generator requires significantly less time (reduces time by several orders of magnitude).

The Creonic CCSDS high performance modulator performs all tasks of an inner transmitter. The modulator expects SCCC (Serial Concatenated Convolutional Code) encoded frames as input and performs mapping, Physical Layer (PL) framing and modulation. In addition, the core performs baseband interpolation and output gain adjustment. The output of the core is designed to be followed by a DAC and RF front end.

The Creonic CCSDS 231.0 LDPC IP supports the LDPC coding schemes as defined by the CCSDS standard.

The IP cores are available for ASIC and FPGAs (AMD Xilinx, Intel).

The recommended CCSDS 131.2-B-1 standard introduces a Serial Concatenated Convolutional Code (SCCC). Main goal of this code is to allow an efficient use of available bandwidth, by allowing to select from 27 valid configurations with a wide range of constellations, block lengths and code rates. The outstanding error correction performance of the SCCC code in combination with the high data rates makes this IP core the ideal fit for further applications where high throughput and high spectral efficiency is key for operation.

Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable TV (CATV) system. It is employed by many cable television operators to provide Internet access over their existing hybrid fiber-coaxial infrastructure. The Creonic LDPC Decoders covers all logical channels of DOCSIS 3.1:

• The Downstream (DS) Data Decoder decodes payload data with very high throughputs.
• The PLC (Physical layer Link Channel) Decoder decodes PLC frames and therefore allows conveying the physical properties of the OFDM channel.
• The Downstream (DS) NCP (Next Codeword Pointer) Decoder decodes NCP frames and therefore allows to convey plenty of information on the OFDM structure.

However, the high flexibility in block lengths and code rates makes it the ideal fir for further applications.

MIMO (Multiple Input Multiple Output) techniques are being used more and more in recent and upcoming standards since they drastically outperform traditional SISO (Single Input Single Output) techniques in terms of maximum throughput and range. This gain results from an increased spectral efficiency, lowering the overall system costs.

A Minimum Mean Square Error (MMSE) MIMO detector is an integral part of a MIMO receiver. The Creonic MMSE detector offers high throughputs even on low-cost FPGAs and convinces with a low implementation complexity at the same time.

Polar codes are a trending family of forward error correction codes currently gaining a place in the realm of digital communications, which exhibit a particularly high performance while requiring a low-complexity implementation. They were first adopted by the 3GPP 5G NR standard.

Rate-Flexible Polar Encoder
The Creonic Polar Encoder IP core is a scalable solution featuring code-rate flexibility, high throughput and very low latency on state-of-the-art FPGAs. Since a polar encoder normally requires information data to be presented in a certain way at its input, the Creonic Polar Encoder IP takes care of this in a pre-encoding stage. This important feature, with aid of AXI4-Stream interface ports, allows a very straight-forward integration of the core into any system.

The Optical Communications Terminal (OCT) Standard was developed by the Space Development Agency (SDA) with the purpose of bringing interoperability across freespace optical communication (FSO) systems where at least one endpoint is a space-based terminal.

The Creonic SDA OCT V3.0 Encoder is designed to generate Over-The-Air (OTA) frames in accordance with the OCT standard. These frames consist of a preamble, followed by a header and payload data, both of which are protected with cyclic redundancy check (CRC) and forward error correction (FEC) for better data integrity.

The Creonic SDA OCT V3.0 Decoder performs the synchronization of the Over-The-Air (OTA) frame and then decodes the header and payload data within the frame.

BCH codes are widely used where bit errors are scattered randomly within the codeword. The Creonic Ultrafast BCH Decoder is capable of processing an entire BCH codeword per clock cycle in a pipelined way. Therefore, tt achieves outstanding data rates.

The design can be parameterized at design-time to support different codeword sizes and code rates. Latency can be adjusted by insertion or removal of pipeline register stages.

Convolutional codes are widely adopted in wireless communication systems for forward error correction. Creonic offers you an open source Viterbi decoder with AXI4-Stream interface, that is capable of decoding most of the convolutional codes as defined by various standards.

The Creonic Wideband Digital Down Converter (DDC) digitally converts the input signal at IF frequency down to baseband by multiplying input samples with sine/cosine waves generated by numerical controlled oscillators (NCO). Down converted samples are then decimated by
a factor ranging from 2 to 512 with multiplying step of 2. A CIC and 4 stages of half band filters are integrated within the decimator.

The core accepts a real signal at input and provides complex I/Q baseband data at the output. The parallel architecture of the core allows for an input throughput up to 2.4 Gsps, data symbol rate up to 540 Msymb/s, making it a perfect fit for ultra high throughput applications such as wideband DVB-S2X communication.

The solution from Creonic for data rates of up to 1 Gbit/s offers outstanding efficiency in terms of implementation complexity. Area and energy efficiency played a decisive role during the LDPC code design process. With this unified approach not only outstanding efficiency is
obtained, but also excellent error correction performance, outperforming Viterbi decoders by up to 3 dB. At the same time, a throughput of hundreds of Mbit/s can be achieved even on low-cost FPGAs.
