Abstract

This paper presents a real-time LTE signal processing system based on general purpose processor (GPP) platform. LTE is one of the wideband wireless communication systems with strict requirements of performance and real-time. To meet these requirements, high-efficiency implementation methods such as SIMD instructions and multicore processing are applied to the system for accelerating the processing. Finally, we achieved an effective LTE eNodeB prototype on commodity PC platform with a low processing latency. The prototype supports most functions of MAC and PHY and reveals the feasibility of realizing real-time high-throughput signal processing systems based on GPP platform.
