Abstract :
The long term evolution (LTE) standard for uplink transmission is based on single carrier frequency division multiple access (SC-FDMA) maintaining low peak-to-average power ratio (PAPR), which is very valuable for the practical handset design. Recently the usage of codebook-based precoding has been 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 a nonlinear transmit power amplifier model in the uplink, EGT is superior to any other precoding schemes. Theoretical analysis of precoding schemes´ PAPR is presented under a quasi-static flat fading channel, and link-level bit error rate (BER) is simulated to corroborate the anticipated results.
