| Abstract(in English) | The channel capacity of AWGN (additive white Gaussian noise) channel is known to be 1/2 log(1+SNR), where SNR is signal-to-noise ratio, and the capacity-achieving distribution (CAD) is Gaussian distribution. However, the capacity is obtained under the average input power constraint, and the modulation scheme having such CAD is not feasible since practical communications systems have a constraint on the peak input power as well. On the other hand, the CAD of the AWGN channel under the peak power constraint is known to be the discrete distribution instead of the Gaussian distribution. In this paper, we compare the CADs of the AWGN channel under peak power constraints and signal constellations of practical discrete modulations, and discuss the practical strategy for adaptive modulation and coding (AMC) by comparing the channel capacity, achievable rates with common modulation schemes, and the actual rates with AMC using LDPC (low-density parity-check) codes. |
