[Discuss-gnuradio] Channel Model

[monika bansal]

Hii

I am using channels.channel_model as

channels_channel_model_0 = channels.channel_model(

noise_voltage = self.EbN0_to_noise_voltage(EbN0),

frequency_offset=0.0,

epsilon=1.0,

taps=(1.0 + 0j, ),

noise_seed=RAND_SEED,

block_tags=True

)  

in the place of Add and Noise_Source in berawgn.py file.. But the BER is not following the theory curve. I am attaching the curve i got.

What does this channel model do ? Can someone please explain it.
