Joint Transmit/receive Frequency-domain Equalization for Broadband Mobile Radio
نویسندگان
چکیده
Frequency-domain equalization (FDE) based on the minimum mean square error (MMSE) criterion can exploit the channel frequency-selectivity to obtain the frequency diversity gain and therefore, improve the bit error rate (BER) performance of broadband single-carrier (SC) signal transmissions in a severe frequency-selective fading channel. However, the performance improvement is limited by the residual intersymbol interference (ISI) which is present after MMSE-FDE. In this paper, to reduce the residual ISI, we propose a joint transmit/receive MMSE-FDE (double MMSE-FDE) for broadband SC block signal transmissions. BER performance improvement is confirmed by computer simulation.

Performance Evaluation for Frequency-domain Pre-equalization with Space-Time block coding Transmit/Receive diversity in DS-CDMA Mobile Radio
Abstract Recently, frequency-domain pre-equalization (pre-FDE) transmission has been attracting attention for improving the SC transmission (e.g., DS-CDMA) performance in a frequency-selective fading channel. Antenna diversity reception is also a well-known technique for improving the transmission performance. However, so far the joint use of pre-FDE and the receive diversity has not been discu...

In this paper, joint transmit/receive frequency-domain equalization (FDE) is proposed for analog network coded (ANC) singlecarrier (SC) bi-directional multi-antenna relay. In the proposed scheme, diversity transmission using transmit FDE is performed at relay station (RS) equipped with multiple antennas while receive FDE is carried out at base station (BS) and mobile terminal (MT) both equipped...

In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

Recently, we proposed space-time block coded-joint transmit/receive antenna diversity (STBC-JTRD) for narrow band transmission in a frequency-nonselective fading channel; it allows an arbitrary number of transmit antennas while limiting the number of receive antennas to 4. In this paper, we extend STBC-JTRD to the case of frequency-selective fading channels and propose frequency-domain STBC-JTR...
