- Abstract
In order to increase bandwidth efficiency of band limited communication system, a new multi-band digital modulation scheme based on Quaternary Carrier Orthogonal Sinusoidal Non-linear Chirp Keying (QCO-SNCK) is proposed. Firstly, by analyzing the orthogonality of SNCK modulated waveform samples, 4 mutually orthogonal waveform samples are selected as a set of new orthogonal subcarriers. Secondly, by using coherent demodulation method in the receiver, the quaternary wireless digital communication system has been achieved. Then the MATLAB software simulation platform is built to analysis the performance of the QCO-SNCK system. Theoretical and simulation results show that: when the communication channel bandwidth is limited, the bandwidth efficiency of QCO-SNCK system is 2 times wider than that of SNCK. Compared with Quadrature Phase Shift Keying (QPSK), the bandwidth efficiency of QCO-SNCK system has adjustable performance and higher flexibility. In addition, QCO-SNCK system has a strong ability of resisting Doppler frequency shift (DFS) which can be applied to wireless communication system with high rate mobile communication terminals.
