| Summary: | The invention discloses a channel estimation method based on an interference environment, and belongs to the field of wireless communication. According to the method, on the premise of saving transmission resources, the calculation steps of the channel estimation method are simplified. Conjugate correlation accumulation is carried out by using two paths of received signals and known PN code sequence sliding, and finally a dispersion pilot frequency length is divided, so that an accurate time domain channel impulse response estimation value is obtained. Accurate estimation of the channel in an interference environment is ensured, and demodulation performance is improved. And finally, eliminating the influence of inter-symbol crosstalk by adopting a fractional frequency domain equalizer, and ensuring the accuracy of the demodulated signal. By using the channel estimation method and the equalization method provided by the invention, the bit error rate (BER) performance can be effectively improved.
