我们利用两跳多端X通道中的计算和反向计算和反向方案。我们介绍了波束形成问题，并将数值结果与解释和前向的网络编码方案进行了比较。此外，我们得出条件，在该条件下，计算和反向计算和向前的总和比网络编码和解码更高的总和率更高。最后，我们通过数值模拟说明结果。
We utilize the compute-and-forward and inverse compute-and-forward schemes in a two-hop multi-antenna X-channel. We introduce the beamforming problems and compare numerical results to a network coding scheme with decode-and-forward. Furthermore, we derive conditions under which compute-and-forward and inverse compute-and-forward achieve higher sum rate than network coding and decode-and-forward. Finally, we illustrate the results by numerical simulations.
