Performance Analysis of Joint STTD and Receive Antenna Diversity with MMSE-FDE for OFDM/TDM

چکیده
Abstract: In this paper, a theoretical BER analysis of orthogonal frequency division multiplexing combined with time division multiplexing (OFDM/TDM) is presented for joint use of space-time transmit diversity (STTD) and receive antenna diversity with minimum mean square error (MMSE) frequency-domain equalization (FDE). The conditional BER expression is derived, based on a Gaussian approximation of the inter-symbol interference (ISI) arising from channel frequency-selectivity, for the given set of channel gains. The average BER performance is evaluated by Monte-Carlo numerical computation method using the derived conditional BER expression.

Joint use of STTD and Antenna Diversity for OFDM/TDM
Abstract: Orthogonal frequency division multiplexing (OFDM) combined with time division multiplexing (TDM) can bridge the conventional OFDM and single carrier (SC) transmission by using minimum mean square error (MMSE) frequencydomain equalization (FDE). The channel frequency-selectivity can be exploited by MMSE-FDE to improve the bit error rate (BER) performance. A much better BER performance ...

In this letter, we introduce frequency-domain spacetime transmit diversity (STTD) encoding/decoding to orthogonal frequency division multiplexing combined with time division multiplexing (OFDM/TDM) on a frame-by-frame basis (i.e., over several concatenated OFDM signals in the frequency-domain) to achieve both spatial and frequency diversity gains and improve the bit error rate (BER) performance...
متن کاملPerformance Improvement by Frequency-Domain Interleaving for OFDM/TDM Using MMSE-FDE in a Wireless Channel
The use of frequency-domain interleaving on a frame-byframe basis for orthogonal frequency division multiplexing (OFDM) combined with time division multiplexing (OFDM/TDM) is presented. In conventional OFDM, FDE is not designed to exploit the channel frequencyselectivity and consequently, the frequency diversity gain cannot be obtained. To further improve the bit error rate (BER) performance of...
متن کاملHARQ Throughput Performance of OFDM/TDM Using MMSE-FDE in a Frequency-selective Fading Channel
Throughput is an important performance measure for data communications over a wireless channel. Orthogonal frequency division multiplexing (OFDM) with hybrid automatic repeat request (HARQ) achieves a good throughput performance over a frequency-selective fading channel. In OFDM with HARQ, however, during the first transmission uncoded information packet is transmitted. Consequently, the channe...
متن کاملPerformance Comparison between CDTD and STTD for DS-CDMA/MMSE-FDE with Frequency-Domain ICI Cancellation
Frequency-domain equalization (FDE) based on the minimum mean square error (MMSE) criterion can provide a better bit error rate (BER) performance than rake combining. However, the residual inter-chip interference (ICI) is produced after MMSE-FDE and this degrades the BER performance. Recently, we showed that frequency-domain ICI cancellation can bring the BER performance close to the theoretica...
