Based on the planned cells, the traffic performance of the Mobile WiMAX for multimedia services are simulated to observe the relationship among vehicle speed, MIMO antenna mode, operation environment and channel throughput. The effect of user mobility on the handoff rate for new generation and handoff calls is considered in the simulations. The channel(More)
Based on the constellation diagram of the different modulations, a novel S and Π-decision rule is designed for the analog demapper of the orthogonal frequency-division multiplexing (OFDM) systems. The dedicated short-range communications (DSRC) system is chosen as an OFDM platform to compare the performance among the proposed S and Π-decision decoder,(More)
