【Abstract】 Aiming at the difficulty of implementing broadband DBF with low latency and high throughput in 5 G communication, a low latency and low complexity real-time DBF implementation scheme is designed. The scheme optimizes the key technologies such as digital orthogonal transform and digital channelization, which effectively reduces the complexity and computation delay of the system. The implementation of hardware system based on FPGA shows that the actual delay of the scheme is only 1.568 μs, which achieves better design performance.更多还原
