In this letter, a fixed-power variable-rate turbo coded modulation scheme for orthogonal frequency division multiplexing (OFDM) is proposed and subband adaptation algorithm based on capacity evaluation is presented. Our object is to improve the overall throughput under target bit-error-rate (BER). Simulation results show that our adaptive OFDM scheme exhibits an about 2.5-5 dB signal-noise-ratio (SNR) gain with target BER of 10^<-4> and subband number of 16 relative to fixed threshold adaptive turbo coded modulation. Moreover, unlike fixed threshold adaptation, with the number of subband decreased, throughput performance is not degraded due to our capacity evaluation algorithm.
