Abstract:In this work, joint transceiver filter design for channel shortening equalization is studied for a multiuser multiple input multiple output (MIMO) frequency selective channel. We develop algorithms for the multiuser MIMO, broadcast, multiple access, and interference channel models, where the link between these models is established via channel duality. We also provide an algorithm for full equalization of these channel models as a special case of the proposed channel shortening equalizer. The main contributions of this paper are investigating the multiuser scenario for the joint transceiver design for MIMO channel shortening equalization and extending the channel duality theorem to shortening equalization and full equalization problems.

“…FD-MC-CDMA [1]- [3] is a frequency based multiple access architecture that combines the best parts of frequency division multiple access (FDMA) and multi-carrier code division multiple access (MC-CDMA) [4]- [7] to simultaneously exploit frequency diversity and minimize multiple access interference (MAI). It is well-known that MC-CDMA can achieve high diversity gain in frequency selective fading channels by simultaneously transmitting over N multiple subcarriers, and separating the signal into subcarriers at the receiver providing for excellent BER performance.…”

Abstract-FD-MC-CDMA is an attractive frequency domain CDMA system that provides high performance in multi-path fading channels by exploiting both diversity gain and multi-user detection (MUD) gain. In FD-MC-CDMA, by decomposing the entire subcarrier set into multiple non-contiguous subcarrier sets, the number of interfering users within each subcarrier set is significantly reduced. As a direct result, an optimal maximum likelihood MUD receiver can be implemented at low complexity. In this paper, we first revisit previously developed phase rotation spreading code design to bring signal space diversity to conventional MC-CDMA systems. Similarly, due to the binary nature of the spreading codes, full diversity is not always exploited in FD-MC-CDMA system. Then we combine the phase rotated spreading code design scheme with FD-MC-CDMA system to exploit full diversity. With the phase rotated spreading codes and the exploitation of full diversity, the new FD-MC-CDMA system offers significant performance enhancement compared with the original FD-MC-CDMA system along with conventional MC-CDMA system. Simulation results over multi-path fading channels confirm the performance gain of the proposed scheme.
