Nas comunicações móveis, o canal consiste em muitos caminhos resolúveis com diferentes atrasos de tempo, resultando em um canal com desvanecimento severamente seletivo em frequência. A equalização no domínio da frequência (FDE) pode aproveitar a seletividade do canal e melhorar o desempenho da taxa de erro de bit (BER) da transmissão de portadora única (SC). Recentemente, a multiplexação multientrada e multisaída (MIMO) está ganhando muita atenção por alcançar transmissões de dados em altíssima velocidade com largura de banda limitada. A multiplexação por divisão de espaço Eigenbeam (E-SDM) é conhecida como uma das técnicas de multiplexação MIMO. Neste artigo, propomos SC E-SDM no domínio da frequência para transmissão SC. No SC E-SDM de domínio de frequência, os canais de transmissão ortogonais para transmitir diferentes dados em paralelo são construídos em cada frequência ortogonal. Em um receptor, o FDE é usado para suprimir a interferência entre símbolos (ISI). Neste artigo, são aplicadas a alocação de potência de transmissão e a modulação adaptativa baseada nos ganhos equivalentes do canal após a realização do FDE. O desempenho do BER do SC E-SDM no domínio da frequência em um canal de desvanecimento Rayleigh com seleção de frequência severa é avaliado por simulação computacional.

Abstract: In mobile communications, the channel consists of many resolvable paths with different time delays, resulting in a severely frequency-selective fading channel. The frequency-domain 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 multi-output (MIMO) multiplexing is gaining much attention for achieving very high speed data transmissions with the limited bandwidth. Eigenbeam space division multiplexing (E-SDM) is known as one of MIMO multiplexing techniques. In this paper, we propose frequency-domain SC E-SDM for SC transmission. In frequency-domain SC 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 inter-symbol interference (ISI). In this paper, the transmit power allocation and adaptive modulation based on the equivalent channel gains after performing FDE are applied. The BER performance of the frequency-domain SC E-SDM in a severe frequency-selective Rayleigh fading channel is evaluated by computer simulation.
