Abstract

In this paper, we propose a new architecture of digital automatic gain control (AGC) for a wideband code division multiple access (WCDMA) receiver. The feature of the proposed architecture is simplicity, in that it does not utilize complicated mathematical functions such as log and its inverse. When the proposed algorithm is implemented using a field programmable gate array (FPGA) device, the number of slices used to implement is 130 over the total of 5120 slices (less than 3%) with 61.44 ㎒ clock. This algorithm has been successfully applied to commercial WCDMA base stations.
