In this paper, we propose a Frequency Domain Equalizer (FDE) without inserting the Guard Interval (GI) at the transmitter in the Wide-band Code Division Multiple Access (WCDMA) system. The proposed FDE adopts the Overlap-Cut (OC) method to avoid the Inter-Block Interference (IBI) and exploits the decision feedback structure to improve the Bit Error Rate (BER) performance. Without inserting the GI, the proposed FDE will be more compatible to the frame format of the current High Speed Downlink Packet Access (HSDPA).
