Multicarrier modulation formats have been chosen for some wireline and wireless communication systems. These systems use the Fourier transform to convert a convolutive channel into multiple memoryless subchannels, which allows for simple equalization at the receiver. However, because the received signal is windowed in time, noise is spread between subchannels. As a result, narrowband interference sources can degrade the performance over a large number of subchannels. Receiver windowing has been proposed as a computationally efficient technique for reducing noise spreading in multicarrier communication systems. We propose a receiver window design algorithm which minimizes the noise power of the demodulated multicarrier signal. Simulations demonstrate the effectiveness of the windows on a variety of different channels and noise sources
