Sample of the main paper: There has been a tremendous growth in wireless communication technology over the past decade. The significant increase in subscribers and traffic, new bandwidth consuming applications such as gaming, music down loading and video streaming will place new demands on capacity. The answer to the capacity demand is the provision of new spectrum and the development of a new technology – Wideband CDMA. WCDMA (Wideband Code Division Multiple Access) is by far the most widely adopted 3G air-interface technology in the new IMT- 2000 frequency bands. Standardized by 3GPP and ITU, WCDMA has gained broad acceptance within the wireless communication industry. WCDMA was designed to provide cost-efficient capacity for both modern mobile multimedia applications and traditional mobile voice services. One of the key benefits of the technology is efficient, flexible support for radio bearers, in which network capacity can be freely allocated between voice and data within the same carrier. WCDMA also supports both multiple simultaneous services and multimedia services comprising multiple components with different service quality requirements in terms of throughput, transfer delay, and bit error rate. In WCDMA, user data is spread over a bandwidth of circa 5 MHz. The
wide bandwidth supports high user data rates and also provides performance benefits due to frequency diversity. The wideband carrier is also cost-effective as more users can be served by means of a single transceiver.
