Neste artigo, a precisão da estimativa da resposta de frequência do canal (CFR) de acordo com o critério dos mínimos quadrados (LS) com duas antenas de transmissão para o sistema de multiplexação por divisão de frequência síncrona-ortogonal no domínio do tempo (TDS-OFDM) é investigada. Para minimizar a variância da estimativa, as condições para orientar o projeto da sequência de pseudo-ruído (PN) são discutidas e três esquemas de projeto de sequência de treinamento são propostos de acordo. Simulações mostram que o esquema de projeto de sequência PN proposto é eficaz, enquanto a complexidade de implementação para a estimativa do canal é baixa.

Abstract: In this paper, estimation accuracy of channel frequency response (CFR) according to least squared (LS) criterion with two transmit antennas for the time domain synchronous-orthogonal frequency division multiplexing (TDS-OFDM) system is investigated. To minimize the estimation variance, the conditions to guide the pseudo-noise (PN) sequence design are discussed and three training sequence design schemes are proposed accordingly. Simulations show that the proposed PN sequence design scheme is effective, while the implementation complexity for the channel estimation is low.
