**transformer coupled nrz matlab**

hi all,

i do need help on my project. i've been building an simple RF system but i need some method:

1) to proof that manchester coding is better than NRZ. some mathematical model/ simulation might help and clarify more.

2) probability test upon the codes that were used. right now i'm pumping a 17 bits code into the system. i do need to know the risk of failure to decode for each series of bits in a 2kHZ code signal with a carrier frequency at 315MHz.

3) to proof that FM system is more effective to avoid collision compared to AM system.

4) code correction can be implemented in one way communication (but i don't know how :? )

if anybody knows.. please help

thanks.
