Study on The Optimum Power Allocation Algorithm Based on Adaptive Allocation Technology

摘要：

According to the instantaneous estimate of sub channel, adaptive allocation technology dynamically allocated number of bits transmitted and the transmit power, optimizing the overall performance of OFDM system. Having described the two basic principles of adaptive power allocation in the OFDM, and on the basis of this principle detailedly discussed three kinds of algorithms: adaptive bit allocation algorithm that is based on the capacity optimization, optimum power allocation algorithm based on the best bit error rate and the second-best power distribution algorithm. Through the system simulation using MATLAB software, characteristics and performance of three kinds of algorithms are analyzed and compared > which are in different channels and environments . Simulation results show that adaptive allocation technology can optimize the capacity of the system and bit error rate.
