Dear experts, I have some questions about the B210 and need some help. When I was using the Matlab to develop the B210, I had some unexpected things. When I send a string of data bits, the image produced by the receiver is always in the form of a sine wave. Especially when I send a string of all 1 bits, the received waveform is a standard sine wave. Why is this? I need some help to solve this problem. Thank you.
