LDPC Code Design for MMSE Turbo Equalization Conference Paper uri icon

abstract

  • The design of low density parity check (LDPC) codes with minimum mean squared error (MMSE) turbo equalization for intersymbol interference (ISI) channels was examined. Techniques to compute the probability density function (pdf) of the extrinsic information at the output of the equalizer and the decoder were used to derive the thresholds for LDPC codes. The input-output pdf of the equalizer was expressed in closed form and evaluated analytically in the design process.
