Turbo-coded Hybrid ARQ for DS-CDMA with Frequency-domain Equalization
نویسندگان
چکیده
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 the frequency-selectivity of the channel. Hence, the throughput is also higher than that with rake combining for all channel conditions. Keyword mobile communications, DS-CDMA, hybrid ARQ, frequency-selective channel

In this paper modified ARQ (automaticrepeat-request) techniques based on turbo coding are investigated for asynchronous DS-CDMA (directsequence code-division multiple-access) data networks under shadowing and frequency selective fading channel conditions. The throughput, delay, and energy efficiency performance of standard ARQ, metric combining, and RCPT (rate compatible punctured turbo) coded ...
متن کاملDS-CDMA HARQ with Overlap FDE
Turbo coded hybrid ARQ (HARQ) is known as one of the promising error control techniques for high speed wireless packet access. However, in a severe frequency-selective fading channel, the HARQ throughput performance significantly degrades for direct sequence code division multiple access (DS-CDMA) system using rake combining. This problem can be overcome by replacing the rake combining by the f...
متن کاملRate Compatible Punctured Turbo-Coded Hybrid ARQ for OFDM in a Frequency Selective Fading Channel
Recently orthogonal frequency division multiplexing (OFDM) has gained a lot of attention in mobile radio communications because of its ability to allow high data rate transmission in a severe frequency selective fading channel. Rate compatible punctured turbo coded hybrid ARQ (RCPT HARQ) has been found to give improved throughput performance in a DS-CDMA system. However the extent to which the ...
