Abstract

In this paper to improve the capacity and coverage of the channel in WCDMA with OFDM, a concatenation of Wideband Code Division Multiple access (WCDMA) and Orthogonal Frequency Division Multiple Access (OFDM) is used as spreading code. Synchronization error which degrades the OFDM system performance is reduced by implementing Synchronization Algorithm which is used to estimate the offset and by using compensation technique these offsets are reduced which improves the system performance. This concept is implemented in Multi-input Multi-output (MIMO) antenna to boost the capacity of the channel for high data rate transmission.
