Space-Time Turbo Coded Modulation: Design and Applications
A design method for recursive space-time trellis codes and parallel-concatenated space-time turbo coded modulation is proposed that can be applied to an arbitrary existing space-time trellis code. The method enables a large, systematic increase in coding gain while preserving the maximum transmit diversity gain and bandwidth efficiency property of the considered spacetime trellis code. Applying...
متن کاملSpace-time turbo coded modulation for wireless communication systems
High computational complexity constrains truly exhaustive computer searches for good space-time (ST) coded modulations mostly to low constraint length space-time trellis codes (STTrCs). Such codes are primarily devised to achieve maximum transmit diversity gain. Due to their low memory order, optimization based on the design criterion of secondary importance typically results in rather modest c...
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 کاملPerformance Analysis and Constituent Code Design for Space-Time Turbo Coded Modulation over Fading Channels
Recent advances in space-time coding and array processing have lead to substantial improvements in broadband wireless access systems. A design method for constituent recursive space-time trellis codes (Rec-STTrCs) and parallel concatenated space-time turbo coded modulation (STTuCM) was introduced recently as a new framework for building low complexity, large equivalent constraint-length STTrCs....
متن کاملSpace-Time Polar Coded Modulation
The polar codes are proven to be capacity-achieving and are shown to have equivalent or even better finite-length performance than the turbo/LDPC codes under some improved decoding algorithms over the additive white Gaussian noise (AWGN) channels. Polar coding is based on the so-called channel polarization phenomenon induced by a transform over the underlying binary-input channel. The channel p...
