This paper presents adaptive frequency hopping as a new user allocation scheme for multiuser OFDM. Users are allocated carriers that have the highest SNR of available system carriers. This process is updated regularly to track channel fading. Adaptive frequency hopping greatly reduces frequency selective fading, improves interference rejection, and consequently improves the received SNR. Additionally Doppler spread is minimised due to the avoidance of nulls in the spectrum. These effects… CONTINUE READING
