3GPP compliant coding and modulation for Downlink Physical Shared Channels
The Physical Downlink Shared Channel (PDSCH) is used for downlink data which is shared from the gNB between time and frequency. This channel contains user equipment control messages, downlink user data and system information. The PDSCH channel needs to be designed with flexibility in mind to support various modulation and coding schemes.
AccelerComm’s family of integrated 5G NR channel products, namely PDSCH Encoder and PUSCH Decoder. On this page we detail the PDSCH Encoder which provides Forward Error Correction (FEC) encoding and decoding capabilities along with the complete Quadrature Amplitude Modulation (QAM) modulation and demodulation functionality for downlink data processing in a gNB/base station.
* This IP is implemented as per the latest 3GPP specifications and are compliant with TS 38.211 and 38.212.
* The new QAM modulator functionality complements the existing high performance AccelerComm LDPC and Polar encoder/decoder solutions.
* Like all AccelerComm IP the LDPC and modulator is configurable to several different parallelisms to optimise for SWaP (Size, Weight & Power) of each integration.
