Usually there's little documentation about SDR, but Analog Devices has "recently" released a book, which is available for free: https://www.analog.com/en/education/education-library/softwa...

Also can be bought, but has a quite hefty price tag: https://www.amazon.com/Software-Defined-Radio-Engineers-Trav...

Other good resources are the books and courses on WirelessPi: https://wirelesspi.com/book/
