Design of Spread Spectrum Multicode CDMA Transport Architecture for Multimedia Services
Overview This paper investigates a new application of the well-known Spread Spectrum Code Division Multiple Access (SS-CDMA) techniques to multimedia services related to the development of the next-generation wireless mobile networks interconnecting with a wireline ATM-based broadband network. Such services allow users to share novel multimedia applications without any geographical restrictions. However, since the mobile radio channel has a fixed limited bandwidth, the traditional SS-CDMA system may not be sufficient to accommodate the Variable Bit Rate (VBR) multimedia services requested by multiple mobile users simultaneously. To tackle this difficulty, a MultiCode CDMA (MC-CDMA) technique is proposed to provide multirate multimedia services by varying the number of spreading codes assigned to each user in order to meet its throughput requirement.
