本文介绍了在Sandbridge SB3500处理器上实现3GPP LTE基带处理的系统和计算性能。采用MRC （Maximum Ratio Combiner）和LMMSE （Linear Minimum Mean Square）作为各种下行传输模式的基线接收算法。通过端到端系统仿真，系统性能评估表明，3GPP组发布的一致性测试要求在0.8到2db的设计余量范围内得到满足。我们的LTE类别2实现的计算复杂性使得整个基带处理在一个SB3500处理器中执行。
In this paper, we present the system and computational performance of 3GPP LTE baseband processing implemented on the Sandbridge SB3500 processor. Maximum Ratio Combiner (MRC) and Linear Minimum Mean Square (LMMSE) are adopted to be the baseline receiver algorithm for various downlink transmission modes. The system performance evaluation, through end-to-end system simulations, shows that the conformance test requirements published by the 3GPP group are met with a design margin ranging from 0.8 to 2 dB. The computational complexity of our LTE category 2 implementation is such that the entire baseband processing executes in one SB3500 processor.
