    • New QC-LDPC codes implementation on FPGA platform in Rayleigh fading environment 

      Farid, Ghani, Prof. Dr.; Abid, Yahya, Dr.; Abdul Kader (Institute of Electrical and Electronics Engineers (IEEE), 2011-02-20)
      This paper presents performance of Quasi-Cyclic low-density parity-check (QC-LDPC) codes on a flat Rayleigh fading channels by employing DPSK modulation scheme. The BER curves show that large girth and diversity level ...

    • A new Quasi-Cyclic low density parity check codes 

      Yahya, A.; Sidek, O.; Salleh, M.F.M.; Ghani, F. (IEEE, 2009-12-16)
      This paper proposes a new technique for constructing the Quasi-Cyclic low density parity check (QCLDPC) codes based on row division method. The new codes offer more flexibility in term of girth, code rates and codeword ...

    • Study of direct detection technique for zero cross correlation code in OCDMA 

      Rashidi, C. B. M.; Anuar, Mat Safar; Syed Alwee Aljunid, Syed Junid, Prof. Madya (Institute of Electrical and Electronics Engineers (IEEE), 2010-05-11)
      This paper investigates the performance of direct detection technique for zero cross correlation code in Optical Code Division Multiple Access (OCDMA) which is a better technique to reduce Multi Access Interference (MAI). ...
