Reduced complexity turbo equalization for space-time trellis coded systems

Reduced complexity turbo equalization for space-time trellis coded systems
In this paper, a reduced complexity turbo equalizer referred to as TEQ-IQ, is proposed for space-time trellis coded (STTC) systems using the in-phase/quadrature-phase cancellation technique developed for single-transmitter and single-receiver systems. The TEQ-IQ scheme is capable of approximating the performance of the conventional turbo equaliser (TEQ-CT), while achieving a complexity reduction factor of 1.4 and 468.2 for a 4-PSK 32-state STTC system communicating over two-path and five-path symbol-spaced and equal tap-weight Rayleigh fading channels, respectively.

Abstract

In this paper, a reduced complexity turbo equalizer referred to as TEQ-IQ, is proposed for space-time trellis coded (STTC) systems using the in-phase/quadrature-phase cancellation technique developed for single-transmitter and single-receiver systems. The TEQ-IQ scheme is capable of approximating the performance of the conventional turbo equaliser (TEQ-CT), while achieving a complexity reduction factor of 1.4 and 468.2 for a 4-PSK 32-state STTC system communicating over two-path and five-path symbol-spaced and equal tap-weight Rayleigh fading channels, respectively.
