Development platform implementation and verification for UMTS UE MODEM

In this paper, we present the development platform (DP) of a user equipment (UE) baseband modem in compliance with 3GPP Release 99 FDD specification. The configuration of the development platform and a detailed explanation of test items are described. The functionality and performance of the UE modem and protocol stacks (layer 1 and layer 2/3) are confirmed by HW/SW co-verification using Seamless CVE and call tests using the Anritsu MD8480A base station simulator. Currently, the UMTS UE modem chip based on development platform is implemented in 0.18 /spl mu/m CMOS technology and tests on the chip are in progress.
