Unexplained . What a great podcast . The story ' s are spooky and read very well . I suggest if you are into that go download it . It ' s not biased at all and the music really sets the tone . Don ' t listen with the lights out . And comedy it ' s The Crab Feast . Fuck the crab feast 5 stars <| sep |> I suppose . I bought my last two last month . They were 45 k or so each had to transfer gold from priest exmain . Probably inflated right now because holidays . <| sep |> Yes , w is the parameter for the channel that determines the center frequency . The way we model a normal comm . channel is pretty straightforward . For every frequency we assume some channel gain coefficient , and we assume additive noise . That is if we transmit coswt we expect to receive Awcoswt Nt , where A is the channel gain , and N is an additive noise component generally the pdf is gaussian . More complex sources of noise , like the ones you are describing , are generally given their own channel names . For instance , when transmitter 1 wants to send to receiver A and transmitter 2 wants to send to receiver B but the signals overlap , this is called an interference channel . The capacity region of this basic channel is still unknown . While channels that interfere with themsleves are usually labeled as rayleigh fading channels . This is because when a signal does interfere with itself , small changes in frequency cause large phase shifts in the multiple received copies . These channels are still point to point , and we know how to characterize them . Honestly communications research is one of those things you can not ask enough questions about before you hit a relevant unsolved problem . Some of the largest breakthroughs in my field have had substantial direct impact on people ' s lives . Whenever someone is actually interested on what is actually going on in the system , it is a pleasure to be able to discuss it .
