On channel coding for CDMA over multipath Rayleigh fading channels

1997 IEEE International Conference on Personal Wireless Communications (Cat. No.97TH8338), 2002
This work considers asynchronous DS-CDMA systems with single-user receivers. The focus, is on combined error control/PN sequence spreading. This work shows that the best performance is achieved when all the bandwidth expansion is by error control coding, instead of by PN sequences. This conclusion is valid for all types of fading channels.

Coding for the Rayleigh fading channel

1996
The problem of effective coding for the Rayleigh fading channel is addressed. A signal transmitted over the Rayleigh fading channel experiences quasi-periodic deep fades in the signal amplitude, and random phase shifts. The fades in signal amplitude are the cause of error events and limit the bit error rate of an uncoded system to about 10-4 at a ...

Bandwidth‐efficient turbo coding over Rayleigh fading channels

International Journal of Communication Systems, 2002
AbstractIntroduced in 1993, turbo codes can achieve high coding gains close to the Shannon limit. In order to design power and bandwidth‐efficient coding schemes, several approaches have been introduced to combine high coding rate turbo codes with multilevel modulations.

Turbo decoding on Rayleigh fading channels with noisy channel estimates

1999 IEEE 49th Vehicular Technology Conference (Cat. No.99CH36363), 2003
A new metric for turbo decoding on Rayleigh fading channels with noisy channel estimates is derived. By including the error variance of the channel estimate in the decoder metric derivation, we calculate the correct channel reliability factor for this case.
