[Discuss-gnuradio] Construction of BEC channel

[jacksk1005]

Hi everyone,
I'm a beginner on GNURadio and trying to simulate the Binary Symmetric
Channel and Binary Erase Channel with AWGN. 
So I use a BPSK-mapper at the transmitter and relevant demapper at the
receiver, then mapper-channel-demapper is equivalten to a BSC.

But for construncion of BEC on the basis of changing the BSC simulation, I
have no idea. Can anyone give me some tips?

Many thanks!
Jacksk
