Your Receive side produces N samples – but too slow at some point, leading to your transmitter needing to "invent" an amount P of samples, because it simply has a fixed sample rate. So, now, from the point of view of the transmitter's DAC, N+P sample periods have passed, whereas the receiver's ADC saw N sample periods. This repeats, and every P > 0. Therefore, the delay is always only growing. Best regards, Marcus
