    摘要: Multiple co-channel signals are received at the same time. The co-channel signals are separated and demodulated within a frequency range by using the Doppler shift, or offset, of the co-channel signals. The signals are isolated by determining the peaks of the signals within the subchannel, or bin. A threshold is applied to the peaks to separate signals from noise and clutter. The individual peaks are compared to a baseband frequency to determine the Doppler shift. Those signals above the threshold are processed and demodulated.
