多小区信道估计技术的研究

Study on technology of multi-cell channel estimation

在TD-SCDMA系统中提出基于PIC(并行干扰消除)和SIC(串行干扰消除)的多小区信道估计技术,给出在这两种信道估计模式下多小区联合检测的性能。仿真表明,基于PIC和SIC的多小区信道估计技术可以明显提高系统性能,在采用这两种信道估计方式后,即使使用单小区联合检测也能提高系统性能,其中,基于PIC的多小区信道估计技术与多小区联合检测技术相结合,可以获得更大的增益。

Multi-cell channel estimation was proposed based on Parallel Interference Cancellation（PIC） and Successive Interference Cancellation（SIC） for TD-SCDMA System.The simulation results showed that multi-cell channel estimation based on PIC and SIC could significantly improve the System performance.Finally,the performance of the System with multi-cell joint detection combined with multi-cell channel estimation was studied through simulation.
