چکیده

This paper1 present an interference suppression using subband adaptive array (SBAA) for space-time block coding (STBC) with multiple input multiple output (MIMO) multirate multicode code division multiple access (CDMA) under the frequency selective fading (FSF). The proposed scheme has a flexible configuration which allows base station (BS) to dynamically adapt to multirate transmission requests from mobile stations (MS). At the receiver, the received signal undergoes STBC based subband adaptive array processing at each subband to suppress the intersymbol interference (ISI), multicode interference (MCI) and multiple access interference (MAI) simultaneously. The proposed system is simulated under different channel conditions and is compared against conventional SBAA.

Adaptive CMMSE Receivers for Space-Time Block Coded MIMO CDMA Systems

A technique that can suppress multiple access interference (MAI) in space-time block coded (STBC) multiple-input multiple-output (MIMO) CDMA systems is developed. The proposed scheme, called the constrained minimum mean square error (CMMSE) receiver, is an extension of the method in [4] to MIMO systems. The proposed CMMSE receiver for STBC systems has the identical complexity and rate of conver...

Non-Data Aided Receiver for Space-Time Block Coded CDMA MIMO Systems

A non-data aided Multiple-Input Multiple-Output (MIMO) receiver with multiple access interference (MAI) suppression is proposed for a space-time block coded (STBC) code-division multiple access (CDMA) system under a multipath fading channel. A decision-directed minimum mean-squared error (MMSE) receiver is developed for alleviating performance degradation due to the finite sample effect. Numeri...

Space-Time Chip Equalization for Maximum Diversity Space-Time Block Coded DS-CDMA Downlink Transmission

In the downlink of DS-CDMA, frequency-selectivity destroys the orthogonality of the user signals and introduces multiuser interference (MUI). Space-time chip equalization is an efficient tool to restore the orthogonality of the user signals and suppress the MUI. Furthermore, multiple-input multiple-output (MIMO) communication techniques can result in a significant increase in capacity. This pap...
