Frequency-Domain Eigenbeam-SDM and Equalization for High Speed Data Transmissions
— In wireless communications, the channel consists of many resolvable paths with different time delays, resulting in a severely frequency-selective fading channel. The frequencydomain equalization (FDE) can take advantage of the channel selectivity and improve the bit error rate (BER) performance of the single-carrier (SC) transmission. Recently, multi-input multioutput (MIMO) multiplexing is gaining much attention for achieving very high speed data transmissions under limited bandwidth. Eigenbeam space division multiplexing (E-SDM) is known as one of MIMO multiplexing techniques. In this paper, we propose frequency-domain E-SDM for SC transmission. In frequency-domain E-SDM, the orthogonal transmission channels to transmit different data in parallel are constructed at each orthogonal frequency. At a receiver, FDE is used to suppress the ISI. In this paper, for high spectrum efficiency, the transmit power allocation and the adaptive modulation based on the equivalent channel gains af...
