I. Introduction
OVER the past few decades, wireless communications and networking have experienced an unprecedented growth. Wireless networking has become ubiquitous owing to the great demand of pervasive mobile applications such as video transmission [1], [2]. Code Division Multiple Access (CDMA) is a promising technology used in the current wireless networks and widely adopted for 3G wireless networks. The challenges for transmitting compressed videos over CDMA in real time lie in several aspects. First, CDMA networks are interference limited, and there are limited radio resources such as the transmission power and the total number of pseudo-random codes. In order to accommodate a large number of users with acceptable received quality, one challenge for system design is how to optimally allocate these radio resources. Furthermore, the bit rate of compressed video can be highly bursty due to the difference in video contents and intra/inter coding modes. To achieve the desirable video quality, we need to adjust the system parameters, such as source coding and radio resource allocations, to each video stream dynamically.
