LTE Uplink PUSCH Channel Encoding and Decoding Process with Implementation Details

This code provides a detailed implementation of the encoding and decoding process for the LTE uplink Physical Uplink Shared Channel (PUSCH). In the encoding phase, the implementation utilizes Turbo coding combined with Cyclic Redundancy Check (CRC) for data encoding. The encoded data undergoes modulation to generate modulation symbols, which are then transmitted through the PUSCH channel to the base station. The decoding process involves demodulating received modulation symbols, followed by demodulation and decoding operations to recover the original data. This implementation includes detailed explanations of key algorithms such as Turbo coding polynomials, rate matching, and constellation mapping for different modulation schemes (QPSK, 16QAM, 64QAM). The code structure features modular functions for CRC attachment, code block segmentation, channel coding, and hybrid ARQ functionality, providing users with comprehensive understanding and practical application of PUSCH technology.
