摘要
介绍了一种基于码片交织、重叠剪切(OC)法FDE以及频域中多用户干扰抵消的接收机结构,将接收数据变换到频域,在频域中进行联合均衡和干扰抵消,在保证较好接收效果的前提下,使系统整体运算量大大减小。
One frequency domain multiuser interference cancellation receiver structure based on chip interleaving and overlap-cut （OC） frequency domain equalization （FDE） is proposed. In this structure, the received data is transformed into frequency domain, subsequently combined equalization and interference cancellation is implemented to the data. The structure reduces receiver＇ s complexity while ensuring good performance.
