The Performance of Chirp-BOK Modulation in the Time Fading Channel

In this letter, the performance analysis of chirp-BOK modulation is carried out and the bit error rate (BER) function is derived and the parameters that influence error performance are defined in Additive White Gaussian Noise (AWGN) channel. In wireless communication, Doppler shift is introduced due to the relative movement of transmitter and receiver terminal, it severely affected the performance of general communication system. Based on the parameters analyzed, the closed-form BER performance of Doppler channel is derived and evaluated by simulation. The simulation result indicate that the simulation BER is depend on the time and signal to noise ratio (SNR) and demonstrate the derivation is validity.
