Improved hybrid MMSE detection for turbo-trellis-coded modulation-assisted multi-user OFDM systems - Electronics Letters
A genetic algorithm assisted minimum mean-square error (MMSE) multi-user detector (MUD) is proposed for a turbo-trellis-coded modulation-based space division multiple access aided orthogonal frequency division multiplexing system. The simulation results show that the system employing the concatenated MMSE-GA MUD was capable of achieving a similar performance to that attained by its optimum coun...
متن کاملTurbo trellis coded modulation for transform domain distributed video coding
A transform domain distributed video coding (DVC) codec is proposed using turbo trellis coded modulation (TTCM). TTCM symbols are generated at the DVC decoder using the side information and the parity bits received from the DVC encoder. These generated symbols are used at the TTCM-based DVC decoder to decode the bit stream. Simulation results show that a significant rate-distortion performance ...
متن کاملSpace-Time Turbo Trellis Coded Modulation for Wireless Data Communications
This paper presents the design of space-time turbo trellis coded modulation (ST turbo TCM) for improving the bandwidth efficiency and the reliability of future wireless data networks. We present new recursive space-time trellis coded modulation (STTC) which outperform feedforward STTC proposed by Tarokh et al. (1998) and Baro et al. (2000) on slow and fast fading channels. A substantial improve...
متن کاملNoncoherent detection for trellis-coded MPSK
This letter shows several methods for improving the decoding of noncoherent trellis-coded M -ary phase-shift keying. We propose two new metrics for basic decision-feedback algorithm. These metrics are derived based on the idea of reducing the effect of incorrect amplitude of the reference signal. We also propose a new decoding algorithm that uses a simple way to estimate the metric of the futur...
متن کاملReduced-complexity I/q Turbo Detector for Convolutional-coding Assisted Space-time Trellis Coding
This paper presents a reduced-complexity turbo detector for convolutional-coding aided space-time trellis coded (STTC) schemes. The proposed technique is based on the separate in-phase/quadrature-phase (I/Q) detection principle developed for single-transmitter and single-receiver systems. Essentially, the reduced-complexity I/Q turbo detector (R-TD) decomposes the received signal into its const...
