| Abstract: | Simple closed-form expressions for the probability of error for nonuniform 16-differential amplitude phase-shift-key (DAPSK) signaling over an additive white Gaussian noise (AWGN) and Rayleigh fading channels are presented. The performance of nonuniform 16-DAPSK with punctured convolutional coding is presented. The results show that the coding can be used with nonuniform 16-DAPSK modulation to transmit additional message in radio broadcasting systems with little degradation to the basic message. |
