%X In order to solve the problem of wasting power, proposed a novel adaptive hybrid optimization power allocation algorithm named first-water filling-last-harmonic (FWLH) . Adopted in FLWH algorithm, water-filling algorithm to compute the threshold which was used to estimate the quality of the sub-channels and Harmonic algorithm (HARM) was used to close the sub-channels below the threshold and allocate the power to the ones above the threshold. Simulation results show that the system capacity with FWLH algorithm is quite close to water-filling algorithm and superior to HARM algorithm, furthermore, the system BER (bit error ratio) with FWLH algorithm is about 100 times lower than that of with water-filling algorithm and about 20 times lower than that of with HARM algorithm.
