Um transceptor de baixa relação pico-potência média (PAPR) com uma técnica de chaveamento ortogonal de deslocamento cíclico de frequência de tempo (TF-CSOK) é proposto para o sistema CDMA multiportadora de uplink (MC-CDMA) sobre interferência de acesso múltiplo ( MAI) e canais de interferência multipercurso (MPI). A estrutura de baixa complexidade do sistema TF-CSOK MC-CDMA foi projetada para envolver as técnicas FCSOK e TCSOK para combater os efeitos MPI e MAI, respectivamente. Em particular, na estação inicial, o detector multiusuário emprega a regra de máxima verossimilhança (ML) e as técnicas de desprendimento e desmapeamento TFSOK para adquirir o ganho de modulação M-ária e o ganho de diversidade. Os resultados da simulação mostram que o receptor multiusuário tem robustez contra MAI forte. Além disso, ele supera o sistema convencional de acesso múltiplo por divisão de frequência de portadora única (SC-FDMA) e o sistema MC-CDMA convencional em ambientes MAI e MPI.

Abstract: A low peak-to-average-power-ratio (PAPR) transceiver with a time-frequency cyclic shift orthogonal keying (TF-CSOK) technique is proposed for the uplink multi-carrier CDMA (MC-CDMA) system over multiple access interference (MAI) and multipath interference (MPI) channels. The low complexity structure of the TF-CSOK MC-CDMA system is designed to involve the FCSOK and TCSOK techniques to combat MPI and MAI effects, respectively. In particular, at the besestation, the multiuser detector employs the maximum likelihood (ML) rule and the TFSOK despreading and demapping techniques to acquire the M-ary modulation gain and diversity gain. Simulation results show that the multuser receiver has the robustness against strong MAI. Moreover, it outperforms the conventional single-carrier frequency division multiple access (SC-FDMA) system and the conventional MC-CDMA system under MAI and MPI environments.
