Analysis and Performance of DWPT-OFDM and Sliding Window Techniques

In this work, Discrete Wavelet Packet Transform (DWPT) has been studied extensively, and a new structure for DWPT-OFDM that is based on FFT and Sliding Window is proposed, a new scheme, which combines FFT and DWPT with SW, reduces the Bit Error Rate (BER) performance, and also another model is presents a design of a new DWPT -OFDM with Sub-Sliding window (S-SW). Implementation and verification of the proposal DWPT-OFDM system in Real Time application by using the Small Form Factor (SFF) Software Defined Radio (SDR) based on Digital Signal Processing(DSP).
