The fifth generation mobile communication network will use a high frequency band for a wide bandwidth. However, since the high frequency band also involves high propagation loss and blockage, it is difficult to avoid coverage holes in a communication

A novel analog decoding method using only 90-degree phase shifters is proposed to simplify the decoding method for short-range multiple-input multiple-output (MIMO) transmission. In a short-range MIMO transmission, an optimal element spacing that max
