Robust Spa e-Time Coding for Correlated Rayleigh Fading Channels

Robust 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 ...

Space-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 ...

Performance and Design of Turbo Codes on Rayleigh Fading Channels

Fading in wireless environments is a major obstacle to reliable communications. In order to mitigate the e ects of fading, channel coding is often employed. In this thesis, the performance and design of the channel coding technique, turbo codes, [1] is examined over Rayleigh fading channels. The thesis considers coherent BPSK signaling over both time-correlated and fully-interleaved Rayleigh, s...

Optimal Signal Constellations for Spa e-Time Rayleigh Channels

Analysis and comparison of the 4-PSK and 8-PSK STTC over Rayleigh fading Channels for determining Performance

Demands for capacity in wireless communications, driven by cellular mobile, Internet and multimedia services have been rapidly increasing worldwide. On the other hand, the available radio spectrum is limited and the communication capacity needs cannot be met without a significant increase in communication spectral efficiency. Coding techniques designed for multiple antenna transmission are call...
