CHANNEL ESTIMATION METHOD, APPARATUS AND SYSTEM FOR FREQUENCY-HOPPING SIGNALS

摘要

Provided are a channel estimation method, apparatus and system for frequency-hopping signals, relating to the technical field of communications. The method comprises: when a channel estimation request is received, performing channel estimation on a frequency-hopping signal at each frequency-hopping time slot in received frequency-hopping signals at n frequency-hopping time slots, so as to obtain n channel estimation values, wherein each of the channel estimation values corresponds to one frequency band; and eliminating, in the n channel estimation values, an amplitude difference and a phase difference between two channel estimation values with frequency bands thereof being adjacent, so as to obtain n updated channel estimation values. Since the amplitudes and phases of the n updated channel estimation values are continuous, the n updated channel estimation values are equal to a channel estimation value of one broadband signal, and compared with a channel estimation value of a narrowband signal, the precision of performing parameter estimation according to the channel estimation value of the broadband signal is higher and the effect thereof is better.
