Abstract

This paper describes the design and implementation of wideband code division multiple access (CDMA) modem for the Korea Telecom (KT) International Mobile Telecommunications 2000 (IMT-2000) testbed system. We have been working on two air interfaces, one of which is based on inter-cell synchronous CDMA and the other on inter-cell asynchronous CDMA. Both air interfaces are designed to accommodate chip rates of 4.196, 8.192, and 16.384 Mcps (chip per second) corresponding to radio frequency (RF) bandwidths of 5, 10, and 20 MHz, respectively. These two air interfaces are being implemented in the first and second testbed systems, respectively. In this paper, we focus on the first phase system, especially on the design and implementation of the wideband CDMA modem.
