Seamless handoff scheme for 4G mobile systems based on IP and OFDM


The goal of 4G mobile systems is to provide enhanced services with high data rates, and integrated and converged services with IP-based networks. In order to satisfy the high data rate requirement and support multimedia efficiently, OFDM (orthogonal frequency division multiplexing) has been considered for the modulation and multiple access scheme in 4G… (More)
