Optimum mode-switching-assisted constant-power single- and multicarrier adaptive modulation

  title={Optimum mode-switching-assisted constant-power single- and multicarrier adaptive modulation},
  author={Byoungjo Choi and Lajos Hanzo Hanzo},
  journal={IEEE Trans. Vehicular Technology},
A set of optimum mode-switching levels is derived for a generic constant-power adaptive-modulation scheme based on a closed-form expression of the average bit error ratio (BER) and the average bits-per-symbol (BPS) throughput of the adaptive-modulation scheme. This results in a constant BER, variable-throughput arrangement. The corresponding BPS throughput performance and the achievable signal-to-noise ratio (SNR) gain are investigated for the optimum mode-switching assisted constant-power… CONTINUE READING
