Research and implementation of 5G DBF technology with low delay and high throughput

针对5G通信中宽带DBF的低延迟、大吞吐率的实现难点,设计了一种低延迟、低复杂度的实时DBF的实现方案。该方案对数字正交变换、数字信道化等关键技术进行优化,有效的降低了系统的复杂度和计算延迟。基于FPGA的硬件系统实现表明,该方案的实际延迟仅为1.568μs,达到了较好的设计性能。

Aiming at the difficulty of implementing broadband DBF with low latency and high throughput in 5G 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 1.568μs,which achieves better design performance.
