Hi, My setup consists of two X310s - one transmitter and one receiver - connected with SMA cable. The receiver code has been independently tested by capturing the AP packets. The transmitter code was tested in a software loopback with the receiver. The gains on both sides were adjusted such that t

Hi Marcus, I am working on a Core i7 8GB system, I dont know if its underpowered, if it is I have access to another Corei5 16 GB station. I know this is going to sound dumb but, how does the USRP sink go into burst mode, I was under the impression that USRP could only transmit data continuously. D

Hi, I wrote a matlab scripts that generates the wifi packets for a given payload. The output is of the format I dumped the output in a bin file. It is my understanding that the complex type file source reads the input (bin) file in a gr_complex data type format ie reading 32 bits from the bin file

Hi , I was reading up about the architecture of GNU Radio. Its primarily an inheritance based architecture, the blocks that pass data to other block are actually implemented as subclass and superclass pair. Am I right about this?

Hi , I was working on the Wifi Transceiver Flowgraph. I created a loopback in the flowgraph itself to be sure that atleast the transceiver works in theory. It did work like magic. Next I replaced the loopback with a uhd source and sink and connected the RF frontends using a SMA cable. It fails to
