Abstract

In this paper, power allocation strategy on subcarriers of Multi-carrier Differential Chaos Shift Keying (MC-DCSK) is studied. At first, the MC-DCSK system model with power allocated reference and information subcarriers is presented. Then bit error rate (BER) expression of subcarriers power allocated MC-DCSK system is derived. Based on the BER expression, the optimal subcarriers power allocation strategy is obtained. The BER performance of the subcarriers power allocated MC-DCSK system is evaluated and compared with the conventional MCDCSK system under additive white Gaussian noise (AWGN) and Rayleigh multipath fading channels. Simulation results confirm the significant advantages of the optimal subcarriers power allocation when the number of subcarriers is large.
