This paper presents a new bit and power allocation scheme for OFDM systems with low computational complexity in which the overall transmission power is minimized by constraining the fixed data rate and bit error rate. The algorithm and simulation include two stages. The first stage involves the application of a target BER and SNR of each sub-carrier for a variable-rate bit pre-allocation. The second stage applies greedy and Campello approach to achieve constant channel rate of bit allocation… CONTINUE READING
