Combined time multiplexed pilot (TMP) derotation with descrambling and despreading in data correlators used by rake receivers

摘要

The invention provides a code modification circuit for receiving a descrambling/dispreading code at a first input pair thereof and a pilot derotation code at a second input pair thereof, and arranged to combine the codes to form a combined code for providing to a correlator such that the correlator can recover data or a pilot signal from an input sequence supplied thereto.
