Incoherent detection

WebJul 6, 2024 · In coherent detection, a local carrier mixes with the received radio frequency (RF) signal to generate a product term. As a result, the received RF signal can be frequency translated and demodulated. When using coherent detection, we need to estimate the channel (frequency band). The amount of overhead strongly depends on the channel … WebApr 15, 2024 · For detection of single monochromatic photons, the absorption and incoherent rates of a single subsystem can be optimized to yield ideal detection 22.
