2D极化折叠PoFo简化接收机架构
第二种方法是 2D 极化折叠（PoFo），它简化了接收机架构。该方法在时域中解偏振：Y 偏振分量被延迟并“折叠”到 X 上，DSP 必须从单条路径中解出 X 和 Y 偏振。这使接收机组件减少一半，但 DSP 必须承担解折叠偏振信息的繁重工作，因此需要更大的电带宽。(4/5)
A second approach is 2D Polarization Folding (PoFo), which simplifies the receiver architecture. This approach resolves polarization in the time-domain: the Y-polarization component is delayed and "folded" on to X and the DSP must unfold the X and Y polarization out of the single path. This reduces the receiver components by half, but the DSP has to do the grunt work of unfolding the polarization information and thus needs more electrical bandwidth. (4/5)
