摘要
In this paper, an improvement of the RA (Rate Adaptive) algorithm with alterable allocation step Is proposed. Considering of the requirement on system bit error rate and the restriction on allocated bits In each channel, we compare the performance between the improved algorithm and the traditional RA algorithm. Simulation results show that the computational complexity of the proposed RA algorithm decreases a lot than the traditional algorithm while the capability of system Is increased. So the proposed improved RA algorithm is a promising optimal method for implementation.
