Abstract
In this paper, a VLSI implementation of a multi-standard channel-decoder for EDGE, WCDMA, and CDMA2k convolutional-codes is presented. The new architecture employs the MAP algorithm for convolutional decoding to support soft-outputs. The decoder is designed for base-station applications. The maximum throughput of the decoder is 16 Mbps for WCDMA and CDMA2k, and 70 Mbps for EDGE, at a clock frequency of 200 MHz.
