Abstract

Two novel combined methods for channel estimation are analyzed and compared in terms of BER and complexity. They are introduced in order to increase the system performance when pilots are time-multiplexed with data symbols. The simulation results justify the choice of these methods as viable solutions for downlink wideband code-division multiple access (WCDMA) systems
