Research and DSP Realization on the Improved Algorithms for PUCCH Format 2a/2b in TD-LTE System

Abstract:

In TD-LTE system, the transmitter generates PUCCH format 2a/2b information, including reference signal with 1/2 bits ACK/NACK feedback information, and the receiver first must use blind estimate to get the ACK/NACK feedback information, and then get the channel response of the reference signal symbols, then the channel response of the data symbols is obtained by time domain interpolation algorithm. This paper first introduces the traditional algorithm of d (10) and the existing algorithm, and then proposes an improved algorithms. Though simulation analysis, the improved algorithms are superior to the traditional algorithm, and the LS algorithm is to implement by DSP, after trade-offs between complexity and performance.
