Este artigo relata o desempenho do teste de campo de uma estação base (BS) equipada com um cancelador de interferência linear paralelo de múltiplos estágios para uplink de banda larga CDMA em uma área suburbana. O teste de campo foi realizado com uma estação móvel (MS) desejada movendo-se ao redor da BS e três MSs interferentes fixos tendo um SIR alvo 11 dB maior que o do MS desejado. O teste de campo demonstra claramente que o uso do cancelamento de interferência com um fator de supressão (ou fator de ponderação) adequado pode reduzir a potência de transmissão do MS desejado em cerca de 6 dB. Este desempenho também foi comparado com os dados calculados e verificou-se que o cancelador de interferência funcionava conforme teoricamente esperado. A taxa de captura de energia recebida foi estimada em cerca de 96%. Este artigo estabelece, portanto, que o desempenho do cancelamento de interferência dos sistemas CDMA em campo pode ser encontrado estimando-se a taxa de captura de potência de recepção e os resultados teóricos do cancelamento de interferência.

Abstract: This paper reports the field test performance of a base station (BS) equipped with a linear parallel multi-stage interference canceller for uplink of wideband CDMA in a suburban area. The field test was performed with one desired mobile station (MS) moving around the BS, and three fixed interfering MSs having a target SIR 11 dB higher than that of the desired MS. The field test clearly demonstrates that using interference cancellation with a proper suppression factor (or weighting factor), can reduce the transmission power of the desired MS by around 6 dB. This performance was also compared with calculated data and the interference canceller was verified to function as theoretically expected. The receive power capture ratio was estimated at around 96%. This paper therefore establishes that interference cancellation performance of CDMA systems in the field can be found by estimating the receive power capture ratio and the theoretical results of interference cancellation.
