Performance of Channel Estimation Algorithm with Joint Channel Estimation Scheme

In this paper, multi-cell channel estimation algorithm based on successive interference cancellation (SIC).This channel algorithm is also used for Time Division Synchronization Code Division Multiple Access Systems (TD-SCDMA). TD-SCDMA is the country's standard of 3G mobile telecommunication. This reduces the number of users in each timeslot, which reduces the implementation complexity of multiuser detection and beam forming schemes, but the non-continuous transmission also reduces coverage (because of the higher peak power needed), mobility (because of lower power control frequency) and complicates radio algorithms. In different interference cancellation (IC) schemes is also exist for multiuser detection (MUD) or spatial multiplexing (SM) problems. In interference cancellation scheme the interference reconstruction is cell based. In this paper algorithm develops a multiuser based interference reconstruction with maximum power. Simulate the channel estimation results which are based on SIC and compare those results with existing IC scheme. That’s providing the higher estimation precision and lower complexity.
