چکیده

Abstract In the next generation wireless communication systems, high-speed packet services will be in great demand, and hence error control technique is indispensable. Hybrid automatic repeat request (HARQ) is a well-known important error controlling technique. Joint FDE and inter-chip interference (ICI) cancellation based on the minimum mean square error (MMSE) criterion can achieve frequency diversity gain while suppressing the residual ICI and therefore, provide much better packet error rate (PER) performance for the multicode DS-CDMA than the conventional rake combining. In this paper, we evaluate by computer simulation the throughput performance of HARQ using multicode DS-CDMA with MMSE turbo equalization.

HARQ throughput performance of DS-CDMA frequency-domain equalization with ICI cancellation

Abstract In direct sequence code division multiple access (DS-CDMA), frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion and inter-chip interference (ICI) cancellation can be applied to exploit the channel frequency-selectivity and therefore, can replace the conventional rake combining while offering a much improved bit error rate (BER) performance. In the ne...

Turbo-coded Hybrid ARQ for DS-CDMA with Frequency-domain Equalization

Abstract In this paper hybrid ARQ is applied to DS-CDMA with minimum mean square error frequency-domain equalization (MMSE-FDE). The throughput of turbo-coded HARQ is evaluated in addition to the packet error rate (PER). DS-CDMA with MMSE-FDE can provide much better PER performance than with rake combining in a frequency-selective fading channel and the performance improves with the increase in...

HARQ Throughput Performance of DS-CDMA Using Frequency-Domain ICI Cancellation

The bit error rate (BER) performance of DS-CDMA in a frequency-selective fading channel can be significantly improved by the use of frequency-domain equalization (FDE). However, the presence of a residual inter-chip interference (ICI) after FDE distorts the orthogonality among the spreading codes and the BER performance of the multicode DS-CDMA degrades as the number of multiplex order increase...
