Abstract

The CDMA (Code Division Multiple Access) is classified into two mainstream technologies; CDMA2000 and CDMA-TDD (Code Division Multiple Access with Time Division Duplex mode). Specifically, in China, the CDMA-TDD mode has been used as the standard of 3G mobile network system. In this paper, we investigate the performance of automatic protection switching (APS) of CDMA-TDD wireless communication system, where APS is the familiar technology to guarantee highly reliable communication networks such as an asynchronous transfer mode network. We develop a stochastic model based on a continuous-time Markov chain for the CDMA-TDD wireless communication system with APS, and derive some related quantitative performance measures in terms of Quality of Service (QoS). Throughout numerical experiments, we examine how the design of APS and network affects the performance measures quantitatively.
