System and method for reducing on-chip memory for frame buffer storage in WCDMA receiver

Abstract

reducing chip

A method of reducing an on-chip memory associated with storing frame buffer in WCDMA receiver includes obtaining, at a WCDMA front end receiver, an signal, transmitting, by an analog to digital convertor, input samples to a digital to digital sigma-delta converter, converting, by a sample rate convertor, a sampling rate associated with the input samples to a desired sampling rate for a rake receiver, quantizing, by the digital to digital sigma-delta converter, the input samples with a first number of bits to a converted data samples of a reduced number of bits, storing, at a memory unit, the converted data samples of the reduced number of bits, filtering the noise from the converted data samples to obtain a noise filtered converted data samples of the reduced number of bits, and decoding, at a WCDMA receiver processing unit, the noise filtered converted data samples over an entire radio frame.
