No uplink Evolved UTRA (UMTS Terrestrial Radio Access), o acesso de rádio de acesso múltiplo por divisão de frequência de portadora única (SC-FDMA) foi adotado devido ao seu recurso vantajoso de baixa relação de potência de pico para média (PAPR), que leva a ampla cobertura provisionamento de área com potência de transmissão de pico limitada dos equipamentos do usuário. Este artigo propõe a geração de canal piloto ortogonal usando a combinação de FDMA e CDMA no uplink Evolved UTRA baseado em SC-FDMA. No método proposto, empregamos transmissão distribuída FDMA para acesso simultâneo a usuários com diferentes larguras de banda de transmissão, e empregamos transmissão CDMA para acesso simultâneo a usuários com largura de banda de transmissão idêntica. Além disso, aplicamos uma sequência de código com uma boa propriedade de autocorrelação, como uma sequência de autocorrelação zero de amplitude constante (CAZAC), empregando uma mudança cíclica para aumentar o número de sequências. Os resultados da simulação mostram que o desempenho médio da taxa de erro de pacotes usando um canal piloto ortogonal com a combinação de FDMA e CDMA em um ambiente de seis usuários, ou seja, quatro usuários cada um com largura de banda de transmissão de 1.25 MHz e dois usuários cada um com largura de banda de transmissão de 5 MHz largura de banda de transmissão, empregando turbo codificação com a taxa de codificação de R = 1/2 e a modulação de dados QPSK e 16QAM coincide bem com aquela em um ambiente de usuário único com a mesma largura de banda de transmissão. Mostramos que a estrutura de canal piloto ortogonal proposta usando a combinação de transmissões distribuídas FDMA e CDMA e a aplicação da sequência CAZAC é eficaz no uplink Evolved UTRA baseado em SC-FDMA.

Abstract: In the Evolved UTRA (UMTS Terrestrial Radio Access) uplink, single-carrier frequency division multiple access (SC-FDMA) radio access was adopted owing to its advantageous low peak-to-average power ratio (PAPR) feature, which leads to wide coverage area provisioning with limited peak transmission power of user equipments. This paper proposes orthogonal pilot channel generation using the combination of FDMA and CDMA in the SC-FDMA-based Evolved UTRA uplink. In the proposed method, we employ distributed FDMA transmission for simultaneous accessing users with different transmission bandwidths, and employ CDMA transmission for simultaneous accessing users with identical transmission bandwidth. Moreover, we apply a code sequence with a good auto-correlation property such as a Constant Amplitude Zero Auto-Correlation (CAZAC) sequence employing a cyclic shift to increase the number of sequences. Simulation results show that the average packet error rate performance using an orthogonal pilot channel with the combination of FDMA and CDMA in a six-user environment, i.e., four users each with a 1.25-MHz transmission bandwidth and two users each with a 5-MHz transmission bandwidth, employing turbo coding with the coding rate of R = 1/2 and QPSK and 16QAM data modulation coincides well with that in a single-user environment with the same transmission bandwidth. We show that the proposed orthogonal pilot channel structure using the combination of distributed FDMA and CDMA transmissions and the application of the CAZAC sequence is effective in the SC-FDMA-based Evolved UTRA uplink.
