Frequency domain equalization space-time block-coded CDMA transmission system

In this work we propose a space-time block-coded (STBF) CDMA transmission system suitable for use with frequency domain equalization (FDE) algorithms. We illustrate the FDE by implementing the maximal ratio combining, the zero forcing and the minimum mean squared error single user detection algorithms. A diversity gain analysis is developed and some interesting results are pointed out. It is sh...

Multilayered Space-Frequency Block Coded OFDM Systems

In this paper, we propose a multilayered spacefrequency block coded OFDM system, which is a combination of the vertical layered space-time architecture, known as V-BLAST, and the space-frequency block coded OFDM system. This system is designed to provide reliable as well as very high data rate communications over frequency-selective fading channels with low decoding complexity. Orthogonal Frequ...

Space-frequency Block Coded-joint Transmit/receive Diversity for Multi-carrier Transmission

Space-frequency block coded transmit diversity (SFBC) is under intensive study to improve the transmission performance of multi-carrier transmission in a frequencyselective fading channel. However, in the conventional SFBC, the transmission efficiency degrades when more than 3 transmit antennas are used. Recently, we proposed a spacetime block coded-joint transmit/receive antenna diversity (STB...

Adaptive space-time-frequency-coded UWB system for wireless body area network

Wireless body area networks (WBAN) emerge as one of the main research streams for future wireless communications. One of the candidates for the WBAN physical layer is multiband orthogonal frequency division multiplexing ultra-wideband (MB-OFDM UWB) technology. However, despite its high data rate feature, it performs poorly in the very dispersive WBAN channel. To improve its performance, this pa...

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...
