    • 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 ...
    • Receiver simplification in synchronous communication systems: Simulation study 

      Mohd Fadzil, Ain; Farid, Ghani; Mutamed, Khatib; Syed Idris, Syed Hassan (Institute of Electrical and Electronics Engineers (IEEE), 2008-12-02)
      This paper presents a simulation study for code-division multiplex system over time varying channels. The scheme investigated here uses a precoding technique in the transmitter depending on the channel information, so that ...
