【 摘 要 】

References(5)This letter presents a new Wavelet Packet (WP) OFDM system using a Sliding Window (SW) technique. The SW is used to increase signal orthogonality and thus reduces the Doppler frequency effect in the received data. This is done by reducing the round-off error and long correlation time of the received data. Simulation results show that the proposed system offers significant BER gains over the standard WP-OFDM system without SW under flat fading and the Additive White Gaussian noise (AWGN) channel.
