Abstract:
A channel estimation method suitable for use in a CDMA communications system employs a high order interpolation using four interpolation points per slot. Four FIR interpolation filters (18-21) produce a channel estimate for each quarter of a slot by weighting the summed pilots of four slots by amounts related to pre-computed polynomial co-efficients. The invention has been shown wot mobiles and has the advantage of low computional complexity.
