阵列处理器中改进几乎空白子帧算法的并行化实现
Parallel Implementation of Improved Almost Blank Subframes Algorithm on Array Processor
摘要
Abstract
Inter-cell interference(ICI) coordination appears in the two-layer heterogeneous networks is a hot topic in the current research on heterogeneous network interference.The software implementation of cell range expansion control almost blank subframes(ABS) scheme has the weakness of large amount of data processing and slow speed.Based on the reconfigurable array processor,a dynamic interference coordination method is presented which is ABS parallel implementation hardware implementation scheme.In the cell range expansion,this algorithm dynamically allocates ABS ratio according to the number of users in order to improve the channel capacity of the cell edge users.By pipelining processing between multiple Processing Element(PE) parallel computing,the operation efficiency of the algorithm is improved.The test results show,when 12 PEs are used and scheduled to realize mapping,in 1 983 operation cycle,the performance enhances 77.03% in comparison with single PE.The parallel computing capability of the algorithm is significanty improved and the macro base station user throughput can reach 4.76 Mbit/s.关键词
