Sphere-Packing Modulated Space-Time Coding Using Non-Binary LDPC-Coded Iterative-Detection
, 2008 A recently proposed Space-Time Block Coding (STBC) signal construction method that combines orthogonal design with sphere packing, referred to here as (STBC-SP), has shown useful performance improvements over Alamouti’s conventional orthogonal design. In

New Technique for Improving Performance of LDPC Codes in the Presence of Trapping Sets
EURASIP Journal on Wireless Communications and Networking, 2008 Trapping sets are considered the primary factor for degrading the performance of low-density parity-check (LDPC) codes in the error-floor region. The effect of trapping sets on the performance of an LDPC code becomes worse as the code size decreases. One

Codeword Structure Analysis for LDPC Convolutional Codes
Information, 2015 The codewords of a low-density parity-check (LDPC) convolutional code (LDPC-CC) are characterised into structured and non-structured. The number of the structured codewords is dominated by the size of the polynomial syndrome former matrix

Repeat accumulate code division multiple access and its hybrid detection
, 2008 In this paper, we propose the novel concept of Repeat Accumulate Code Division Multiple Access (RA-CDMA), which employs unique, user-specific channel code generator matrices (interleavers) for differentiating the users.

Differentially Encoded LDPC Codes—Part II: General Case and Code Optimization
EURASIP Journal on Wireless Communications and Networking, 2008 This two-part series of papers studies the theory and practice of differentially encoded low-density parity-check (DE-LDPC) codes, especially in the context of noncoherent detection. Part I showed that a special class of DE-LDPC codes, product accumulate
