Patent ID: 7978752

Claim:
A method for switching operating modes of a receiver receiving data, the method comprising: determining whether a criteria is met to switch the operating mode of the receiver, wherein the criteria for switching the operating mode of the receiver is selected from the group consisting of: a signal to noise ratio (SIR) input, a transport format resource combination (TFRC) input, a delay spread estimate and a power save input; switching the operating mode of the receiver from a first mode to a second mode if the criteria is met; performing a channel estimation on the received data using M number of taps; and performing equalization on the received data using a tap update of L number of taps; wherein the first and second operating modes are selected from the group consisting of an equalizer mode and a matched filter (MF) mode; wherein the first mode is the equalizer mode and the second mode is the MF mode; wherein the receiver is operating in the second mode, further comprising: stopping the equalization of the received data; enlarging the M number of taps, wherein the enlargement of the number of M taps is dynamic; and reassigning equalization resources to channel estimation resources.
