基于GPP的LTE上行链路并行策略研究

3GPP LTE系统需要支持很高的空口速率,这就对基带部分的信号处理时间提出了很高的要求。单线程的串行处理已经很难达到系统要求,需要引入并行化方法来实现高速的数据处理。在英特尔多核处理器上,针对LTE上行物理信道的特点,使用OpenMP并行化方法对上行数据进行了并行化处理,并通过测试比较,验证这种方法取得了很好的效果。

Research of Parallel Strategy for LTE Uplink Channels Based On GPP

3GPP LTE system is required to support very high air interface data rate,thus the baseband digital signal processing should be very fast.Since the serial processing using only one thread can＇t meet the requirement,we need to introduce the parallel method to implement high rate data processing.On Intel multicore processor and according to the feature of physical uplink channels of LTE,we choose to use OpenMP to implement the parallel processing of uplink data.By testing and comparing,we also validated good performance of this method.
