Space-time trellis code construction for fast fading channels
The need for bandwidthand power-efficient wireless communication systems has raised considerable interest in spacetime codes. In this work, we propose a systematic space-time code construction procedure for fast fading channels. The method can be used to design space-time codes for an arbitrary number of transmit antennas and any memoryless modulation. We introduce a new design criterion that e...
متن کاملPerformance of Space Time Trellis Code With Rayleigh Fading Scenario
Space Time Trellis codes provided maximum diversity advantage using simple decoding techniques. However, space-time block codes did not provide coding gain, and nonfullrate space-time block codes introduced bandwidth expansion. In this paper we implement space time trellis code using relay fading scenario. We present here the design of the 4psk with 2 transmit antennas and 1,2,4 receiver antenn...
متن کاملSpace-time signal design for time-correlated Rayleigh fading channels
The existing constructions of space-time codes or modulation have mainly focused on two ideal situations: either quasi-static or rapid fading channels. In this paper, we consider the design of robust space-time modulation for time-correlated Rayleigh fading channels. We show that the space-time signals of square size achieving full diversity in quasi-static fading channels can also achieve the ...
متن کاملRobust space-time codes for correlated Rayleigh fading channels
Space-time (ST) coding has emerged as an effective strategy to enhance performance of wireless communications in fading environments. Many different ST coding schemes have been proposed to achieve reliable communications in independent fading channels. However, a design of robust ST codes for correlated fading channels has not been addressed. In this paper, we propose a simple robust ST coding ...
متن کاملSingle-Carrier Space-Time Trellis and Space-Time Block Coding for Dispersive Rayleigh Fading Channels
In this contribution we propose a novel Space-Time Coding (STC) scheme for transmissions over dispersive Rayleigh fading channels, which invokes a Joint-Detection assisted Minimum Mean Square Error based Decision Feedback Equalizer (JD-MMSE-DFE) for jointly detecting the channel-impaired wideband signals of multiple transmit antennas. The performance of the proposed scheme was investigated usin...
