Title
Capacity and Modulations with Peak Power Constraint
Abstract
Achievable rates with phase shift keying (PSK) and quadrature amplitude modulation (QAM) input constellations for a complex-valued additive white Gaussian noise (AWGN) channel are investigated. The comparison is made under constraints on peak power of the input signal rather than its average power. Capacity and capacity-achieving distribution (CAD) are also computed under the peak power constraint. The comparison reveals that PSK and QAM are close to capacities under different forms of peak power constraint.
