This is my first time to learn about wireless communication, and I don’t know much. I would like to ask you, in wireless communication, what typical circuits are more suitable for the following situat...
1: When I was doing PTR8000 communication, I used the SPI operation protocol, but at that time, I simulated the clock line, MISO, MOSI, and CSN myself. (By the way, there is one thing I don’t understa...
The help manual says: Under normal circumstances, the recv function returns the number of bytes actually received, and returns -1 if the call fails. So, under what circumstances does the call fail? Is...
LDPC code is Low Density Parity Check Code (LDPC). LDPC code was first proposed by Gallager in his doctoral dissertation in the 1960s. However, due to the technical conditions at that time and the lac...
Dear elders
