摘要: A salient advantage of single carrier frequency division multiple access (SC-FDMA) is low peak-to-average power ratio (PAPR) which lower than that OFDMA. Precoding using transmit beamforming (TxBF) a MIMO spatial multiplexing method increases the data throughput significantly. However, when applied to SC-FDMA, it PAPR. In this paper, we describe how can apply TxBF an SC-FDMA system and show its effect on PAPR We then consider effects precoder averaging across subcarriers quantization, typically used reduce feedback overhead, Comparisons are made with antenna, non-precoded (SM) space-frequency block coding (SFBC) systems. Lastly, modest amount amplitude clipping acceptable level virtually no harmful performance or spectral growth.
