Log-likelihood ratio algorithm for use in reducing co-channel interference in wireless communication systems
Abstract:
In one embodiment, an apparatus includes a receiver configured to receive a transmission from a wireless communication device, the transmission associated with resource units, a detector configured to generate log-likelihood ratio data from the received transmission, and a controller configured to calculate noise and interference for each of the resource units and modify the generated log-likelihood ratio data based on the calculated noise and interference.
Abstract(Chinese):

在一个实施例中，一种装置包括：接收机，被配置为从无线通信设备接收传输，与资源单元相关联的传输;被配置为从所接收的传输产生对数似然比数据的检测器;以及被配置为计算噪声的控制器， 对每个资源单元进行干扰，并根据计算出的噪声和干扰修改产生的对数似然比数据。
