Space-time code performance bounds on quasistatic fading channels
We evaluate truncated union bounds on the frame error rate performance of space-time (ST) codes operating over the quasistatic fading channel and compare them to results of computer simulation. Both ST trellis and block codes are considered. We calculate these bounds by characterizing the set of codeword differences from a general expression for the exact pairwise error probability (PEP). We de...
متن کاملWeighted Space Time Trellis Code for Slow Nakagami Fading Channel
It has been well known that the suitable criteria for Space time trellis codes (STTC) designed over slow Nakagami fading channel for product of rank and number of receiver antennas ) are maximization of minimum rank and maximize the minimum product of nonzero eigenvalues for rank and determinant criteria. But for large product i.e. for ), the design of codes with minimum error probability and m...
متن کاملSpace-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 and design of space-time coding in fading channels
The pairwise-error probability upper bounds of space–time codes (STCs) in independent Rician fading channels are derived in this letter. Based on the performance analysis, novel code design criteria for slow and fast Rayleigh fading channels are developed. It is found that in fading channels, STC design criterion depends on the value of the possible diversity gain of the system. In slow fading ...
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....
