I'm transmitting a 16-QAM signal using an NI 2920 USRP. Here is a snapshot of the front panel that is seen (on LabVIEW) -
I'm trying to figure out the bit rate from the given details. The symbol rate is given to be 125k. For 16-QAM, each symbol must be encoded using 4 bits. Does this mean that the bit rate is simply 125k*4 = 500kbps? Do parameters such as the IQ sampling rate and samples per symbol make a difference to the bit rate?
