Closed-Form and Analytical BER Expression for OFDM System with μ-Law Companding Operation被引量：1
《China Communications》2019年第7期61-69,共9页Zhitong Xing Kaiming Liu Yuan’an Liu 
supported by the National Natural Science Foundation of China(61821001/61272518)
The μ-law companding function has been applied widely in orthogonal frequency division multiplexing (OFDM) to reduce the peak-to-average power ratio (PAPR). However, nonlinear distortion caused by the μ-law compandi...
