An Efficient M-ary Modulation Technique using Single Linear Chirp Signal
In recent years, as the indoor wireless communication has gained increasing attention, various kinds of wireless communication techniques has developed rapidly to obtain a better system performance. Chirp signal is also noticed for the feature of low power consumption, high processing gain and low cost A novel M-ary chirp modulation technique is proposed in this paper to increase the system performance both under AWGN channel and indoor wireless channel. Optimal single linear chirp signal is designed in this system to reduce the cross correlation, and simplify the complexity of the system. Simulation shows that, compared with the binary orthogonality modulation technique, the M-ary chirp modulation technique using optimal single linear chirp signal has a high data rate with a reasonable BER both under AWGN channel and indoor wireless channel.
