Abstract :
A fast frequency-hopped (FFH) receiver is described which uses a prewhitening filter to reject narrowband interference. It is shown that using an appropriate fractional tap spacing, the interference can be estimated independently of the desired signal. Bit-error-rate results are presented for the receiver for linear square-law combining. The results compare favorably to those obtained by maximal-ratio combining
