Subcarrier Availability in Downlink OFDM systems with Imperfect Carrier Synchronization in Deep Fading Noisy Doppler Channels
Multicarrier system such as orthogonal frequency division multiplexing (OFDM) is considered as a promising candidate for wireless networks that support high data rate communication. In this paper, we investigate the performance of a multi-user OFDM system under imperfect synchronization which is caused due to noise, Doppler shift and frequency selective fades in the channel. Monte Carlo analysis indicates an average of 22 % loss in the number of allocatable subcarriers under imperfect...[Show more]
