  • Low-density parity-check (LDPC) codes have been accepted as the standard codes for the 5th-generation New Radio (5G NR) standard. The performances of a linear block code LDPC based on the sparse matrix are extremely near to the Shannon limit. Ever since LDPC was invented, continuous encryption algorithms have been introduced, in which two more dominant ones, Quasi-cyclic (QC) LDPC and Repeat Accumulate (RA) LDPC, are referred to as the simple decoding algorithms.

  • Chapter 10 - Error detection and correction. This chapter discusses error detection and correction. Although the quality of devices and media have been improved during the last decade, we still need to check for errors and correct them in most applications.

  • Another class of linear codes, known as Convolutional codes. We study the structure of the encoder. We study different ways for representing the encoder.Convolutional codes offer an approach to error control coding substantially different from that of block codes. A convolutional encoder: encodes the entire data stream, into a single codeword. does not need to segment the data stream into blocks of fixed size (Convolutional codes are often forced to block structure by periodic truncation). is a machine with memory.

  • Evaluating the average probability of symbol error for different bandpass modulation schemes Comparing different modulation schemes based on their error performances. Channel coding: Transforming signals to improve communications performance by increasing the robustness against channel impairments (noise, interference, fading, ..) Waveform coding: Transforming waveforms to better waveforms Structured sequences: Transforming data sequences into better sequences, having structured redundancy. “Better” in the sense of making the decision process less subject to errors....
