Thanks Martin, will look into this. I think we are picking up some very weak interferers too. DH From: Martin Braun Sent: 12 January 2016 07:30 To: David Halls; GNURadio Discussion List Cc: Will Thompson Subject: Re: Schmidl & Cox Detector Noise shouldn'

Noise shouldn't cause false triggers, but if you increase the gain you might see more artefacts (e.g. more DC offset), which will cause false triggers. You can run the block through simulation and see how it behaves. Cheers, Martin On 01/11/2016 11:50 PM, David Halls wrote: > Hi guys, > > >

Hi guys, Happy New Year to everyone. We are using a flow graph based on the OFDM example in GR, including the Schmidl and Cox detector block. Having spread the USRPs out over our test environment we have increased the receiver gain significantly (to about 30dB). (N210 XCVR240 @ 1MS/s, 2.4GHz)
