Generalized discrete fourier transform based improvement of partial transmit sequence scheme to reduce PAPR in OFDM systems

Future applications of communication systems require higher data rates and more mobility. Orthogonal frequency division multiplexing (OFDM) can achieve these goals due to it is ability to reach high bit rates over fading channels as well as its efficient utilization of the bandwidth. However, the...
