How non-coherent detection of FSK works?
Attached figure is the block diagram of non-coherent quadrature receiver of Binary-FSK. Basically, it will use a correlltor to find out the right frequency of input signal.
My question is that how the system knows the right symbol position of do the T-based integration. If the integration is not processed during the right symbol period, it will incur aliasing between adjacent symbols.
