How pskmod.m works? I mean QPSK is supposed to make two bits as input and output one symbol.

But when I use pskmod([1 1 1 1 0 0 0 0],4), the length of the answer remains same i.e. 8 and not 4

I wonder if this is going to affect the BER performance of QPSK in Matlab

I know the solution too that I can use reshape and blah blah blah, but I want to know why Matlab has not made it correct? Maybe it has no affects?

Comments from experts are welcome
 

Do not worry it will not affect the BER calculation but of course the symbol error rate (symerr command) will be different, I have implemented the whole WiMAX using this modulation function and it is accurate.
