i've downloaded this model from the simulink web site only change whihc 
i've made is change the channel type from multichannel to AWGN, i jus 
twant to know that is thier any way that in this simulation that i can 
remove the error coder and error decode from this simulation.

i know what are the blocks which are needed to be removed but i can't 
understand the way these blocks are inter linked, when i remove those 
blocks then this simulation stop working and start throwing 3-4 errors.

any help in this regard will be appreciated
