摘要：
Long term evolution (LTE) standard for uplink transmission is based on single carrier frequency division multiple access (SC-FDMA) to maintain low peak-to-average power ratio (PAPR), which is very valuable for the practical handset design. Recently the usage of codebook-based precoding is thoroughly discussed for the LTE-Advanced (LTE-A) uplink. Among the various precoding schemes, equal gain transmission (EGT) is proposed in this paper because it does not increase any PAPR. Especially, considering nonlinear transmit power amplifier model in uplink, EGT is superior to any other precoding schemes. Theoretical analysis of precoding schemes' PARR is presented under quasistatic flat fading channel, and link-level bit error rate (BER) is simulated to corroborate the anticipated results.
