Hi , I want subtract a transmitted signal with it's received delayed version , the problem is in receive side i sample signal in a uncertain sample time and off course when i subtract that with original signal (after AGC) , it doesn't work at all . Since delay block work only in integer value (one sample) it was not possible i use that for phase aligning two signal , What i did was i interpolate signal pass it through delay block and decimate it again , in this scenario with a interpolation factor of 100 i can get a good phase alignment and subtraction of signals. But the problem is that interpolation and decimation are very inefficient , i can barely get 300Ksps when i use an interpolation factor of 100 , i need at least 10Msps . What is your suggestion ?
Thank you .
