چکیده

Severe frequency-selective fading, encountered in a broadband wireless mobile communication, significantly degrades the bit error rate (BER) performance of direct sequence spread spectrum (DSSS) signal transmission with rake combining. In this paper, frequency-domain pre-equalization transmission, called pre-FDE transmission, is presented for orthogonal multicode DSSS signal transmission. It is confirmed by the computer simulation that pre-FDE transmission can achieve a BER performance almost identical to that attainable by FDE reception. key words: pre-equalization, frequency-domain equalization, direct sequence spread spectrum

Frequency-Domain Pre-Rake Transmission for DSSS/TDD Mobile Communications Systems

In this Letter, a frequency-domain pre-rake transmission is presented for a direct sequence spread spectrum with time division duplex (DSSS/TDD) system under a frequency-selective fading channel. The mathematical relationship between frequency-domain and time-domain pre-rake transmissions is discussed. It is confirmed by the computer simulation that, similar to the time-domain pre-rake transmis...

Joint Frequency-domain Equalization and Antenna Diversity Combining for Orthogonal Multicode DS-CDMA Signal Transmissions in A Frequency-selective Fading Channel

Orthogonal multicode direct sequence code division multiple access (DS-CDMA) has a flexibility in offering various data rate services. However, in a frequency-selective fading channel, the bit error rate (BER) performance is severely degraded since othogonality among spreading codes is partially lost. In this paper, we apply frequency-domain equalization and antenna diversity combining, used in...

Frequency-domain Multi-stage Inter-code Interference Cancellation for Multi-code DSSS Transmission

Frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion can replace rake combining with much improved bit error rate (BER) performance of the multi-code direct sequence spread spectrum (DSSS) signal transmission in a severe frequency-selective fading channel. However, since the channel cannot be completely equalized, the residual inter-code interference (ICI) is ...

Frequency-Domain Space-Time Block Coded-Joint Transmit/Receive Diversity for Direct-Sequence Spread Spectrum Signal Transmission

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...

Pre-equalization for single carrier transmission

Abstract Recently, frequency-domain equalization (FDE) at a receiver has been attracting attention for improving the SC transmission (e.g., DS-CDMA) performance in a frequency-selective fading channel. Authors have been studying frequency domain pre-equalization at a transmitter as an effective technique to improve the transmission performance. In this paper, a pre-equalization transmission in ...
