Multiple input multiple output techniques combined with orthogonal frequency division multiplexing (MIMO-OFDM) provide a promising approach for wireless systems. However, a serious drawback of the OFDM system is the high peak-toaverage power ratio (PAPR), which may severely affect the power efficiency of RF power amplifiers. In this paper, we propose a simple method to reduce the PAPR of MIMO-OFDM signals based on the use of unused subcarriers. Instead of processing the signals at each transmitter separately, a peak cancelling signal is generated at one antenna and is then applied to all the others with only simple modifications. Simulation has shown that a minimum 2 dB reduction in PAPR can be achieved for all transmit signals using this approach. As the signal processing is nearly all done at a single transmitter, repetition of the operations at each transmitter is avoided, and therefore the overall cost of the system can be significantly reduced.

GBSBEM(几何单反射椭圆模型)可以用来仿真功率－延迟－角度（pda-图）、功率延迟图、时间－角度的联合统计、波达方向的边缘特征和窄带衰落包络。适用于低层系统，包括微小区和微微小区、杂波绕射基站天线、发射机到接收机之间以及发射机和接收机的周围充斥着散射体的情形。由于其适用范围广泛且具有解析性质，揭示了空间无线信道不同特征间的相互联系，是进行研究的理想模型。(GBSBEM (geometric GBSBEM) simulation can be used to power-delay-angle (pda- Chart), power plans delayed, time-point joint statistics, DOA on the brink of decline and narrow envelope. Apply to the lower systems, including Microcell and Microcells, Clutter diffraction base station antenna, between the transmitter and receiver to the transmitter and receiver around the full scattering case. Because of its broad scope of application and analytic nature, Space Channel reveals the different features of the inter-linkages Research is the ideal model.)
