- W2159123089 abstract "This paper presents a comparison among the performances of various transmission technologies in a typical indoor radio environment. The performance of fresuency hopping and direct sequence spread spectrum are compared with the performance of multicarrier, decision feedback equalizer, and sectored antenna systems. Given a maximum tolerable outage probability, the m a x i ” achievable data rates are obtained for the different modulation techniques. Outage probabilities are estimated through simulation, using channel impulse responses obtained from ray uacing. The bandwidth efficiency of spread spectrum modulation is shown be very low. For a fixed bandwidth, the minimum power requirement of each modulation technique is also presented, showing significantly lower power xqukments for spread spectrum. Overall, multicarrier modulation is found to present the best tradeoff between bandwidth efficiency and power consumption." @default.
