摘要：
Digital signal processing on high-performance computing platform based on general-purpose processor is one of the development directions of software-defined radio, which provides a new idea for the signal combining of large-scale antenna array. In this paper, two parallel implementations of SUMPLE combined algorithm are proposed, which are multi-antenna-group method (MAGM) based on task decomposition principle and multi-signal-block method (MSBM) based on data decomposition principle. The processing capability and real-time performance of the two methods are analyzed in detail. Results show that MAGM is not suitable for the high-performance computing platform because of large and frequent data transmissions from central processing unit (CPU) to graphics processing unit (GPU). The traditional iterative method of SUMPLE cannot be applied to MSBM due to the dependencies among signal blocks.
