Hi all, I have problem with Simulink solution of 0-bit allocation to one or more carriers in DMT (based on commadsl model).
Need to know way how to insert sample(i.e. 0) to defined position of data flow.

i.e. I have sequence 0 1 0 1 1 1 and I need insert 0 to 2nd and 6th position, that means on the output of "block" will be 0 0 1 0 1 1 0 1. (there is allocated 1bit per carrier a 2nd and 6th carrier is unallocated, then removed on the demodulation block..)

I have idea what to do, but do not know how to do in Simulink :-(

than you for reply
M
