This letter is concerned with a class of nonbinary low-density parity-check (LDPC) codes, referred to as column-scaled LDPC (CS-LDPC) codes, whose parity-check matrices have a property that each column is a scaled binary vector. The CS-LDPC codes, which include algebraically constructed nonbinary LDPC codes as subclasses, admit fast encoding and decoding algorithms. Specifically, for a code over the...
To deal with the short burst signals' combining problem at low Signal-to-Noise Ratio (SNR) in an antenna array, this paper presents a novel combining weights estimate algorithm, called CM-WE, which based on the information mining of the array signals' correlation matrix. Then, it compares CM-WE's performance with SUMPLE algorithm which is commonly used in the Deep Space Network (DSN). Simulation shows...
