Perfomance of RS Coded DS-CDMA Using Noncoherent $M$-ary Orthogonal Modulation over Multipath Fading Channels

Yang, L-L., Yen, K., Dillinger, M. and Hanzo, L. (2000) Perfomance of RS Coded DS-CDMA Using Noncoherent $M$-ary Orthogonal Modulation over Multipath Fading Channels At PIMRC'2000, United Kingdom. 18 - 22 Sep 2000. , pp. 584-588.

Record type: Conference or Workshop Item (Paper)


The performance of Reed-Solomon (RS) coded direct-sequence code division multiple-access (DS-CDMA) systems using non-coherent M-ary orthogonal modulation is investigated over multipath Rayleigh fading channels. Equal gain combining (EGC) diversity reception is invoked and the related performance is evaluated for both uncoded and RS-coded DS-CDMA systems. 'Errors-and-erasures' decoding is considered, where the erasures are based on Viterbi's so-called ratio threshold test (RTT). The performance of the 'errors-and-erasures' decoding technique employing the RTT is compared to that of 'error-correction-only' decoding over multipath Raleigh fading channels. The numerical results show that when using RTT-based 'errors-and-erasures' decoding, RS codes of a given code rate can achieve a higher coding gain than without erasure information.
