Abstract:
High Peak-to-Average Ratio of the transmitted signal is a major drawback of Orthogonal Frequency division multiple accesses (OFDMA). In this paper, we propose a Selected Mapping Technique, Partial Transmit Sequence and Discrete Fourier Transform Spreading Techniques to overcome the problem of high PAPR in Long term evaluation uplink transmitter. Performance enhancement of the OFDM signal uplink transmitter for Long-Term Evolution has been observed and its Peak to average power ratio is investigated through MATLAB simulations.
