We analyze the mobile fronthaul (MFH) bandwidth and the wireless transmission performance in the split-PHY processing (SPP) architecture, which redefines the functional split of centralized/cloud RAN (C-RAN) while preserving high wireless coordinated multi-point (CoMP) transmission/reception performance. The SPP architecture splits the base stations (BS) functions between wireless channel coding/decoding and wireless modulation/demodulation, and employs its own CoMP joint transmission and reception schemes. Simulation results show that the SPP architecture reduces the MFH bandwidth by up to 97% from conventional C-RAN while matching the wireless bit error rate (BER) performance of conventional C-RAN in uplink joint reception with only 2-dB signal to noise ratio (SNR) penalty.
我们分析了在分离物理层处理（SPP）架构中的移动前传（MFH）带宽和无线传输性能。该架构重新定义了集中式/云无线接入网（C-RAN）的功能划分，同时保持了较高的无线协作多点（CoMP）传输/接收性能。SPP架构将基站（BS）功能划分为无线信道编码/解码和无线调制/解调，并采用其自身的CoMP联合传输和接收方案。仿真结果表明，与传统C-RAN相比，SPP架构可将MFH带宽降低多达97%，同时在上行链路联合接收中，在仅存在2 dB信噪比（SNR）损失的情况下，与传统C-RAN的无线误码率（BER）性能相匹配。
