[USRP-users] adaptive modulation using USRP

Hello everyone, I am looking towards how to make a flowgraph to detect when received signal strength is below -20 dB for instance. It'll automatically change modulation techniques to a low-order modulation (QPSK) and when more than -20 dB (say -10 dB). It'll take a high modulation technique (16QAM)

[USRP-users] Calculate packet error rate using rx-ofdm

Hello, I am currently working with USRP for the gr-digital ofdm rx and tx. I want to know any reasonable way to calculate the packet error rate. I am using the signal source at the transmit side while I am planning to get the loss in packet at the receiver side. Currently, i looked at a dated back
