%X Frequency-selective frequency hopping (FH) cosite dinterference is a typical long impulse response interference. The Laguerre structure is a compromise between Finite Impulse Response (FIR) and Infinite Impulse Response (FIR) structure, so the Laguerre filter can match this long impulse response interference effectively and have better stability. Based on the research of the characteristic of the cosite multi-path channel, the new adaptive Laguerre FH cosite interference canceller was proposed, and the algorithm of the canceller and the estimation of the optimum pole of the Lagucrre filter were presented. The simulation results show the new canceller can achieve much better performance of cancellation and stability in both non-time-varying channel and time-varying channel.
