You have windows enabled in the FFTs. Switch to rectangular windows for OFDM (you can check out the OFDM examples). M On 04/16/2016 02:53 PM, Abhinav Jadon wrote: > Hi, > I made two flowgraphs. > 1st flowgraph : Source -> BPSK modulation -> Constellation Sink > 2nd flowgraph : Source -> BPSK modu

[Discuss-gnuradio] OFDM Constellation Issue

2016-04-16 Thread Abhinav Jadon
Hi, I made two flowgraphs. 1st flowgraph : Source -> BPSK modulation -> Constellation Sink 2nd flowgraph : Source -> BPSK modulation -> IFFT -> FFT -> Constellation Sink The source is configured such that if only transmits 1s. Therefore one would expect the constellation plot to have one dot on th
