In M-ary psk(adsbygoogle = window.adsbygoogle || []).push({});

Rb=Rs*log M log with base 2

Rb- bit rate

Rs - symbol rate

then bandwidth required for passband signal is B=Rs

and bandwidth effeciency = Rb/B=log M log with base 2.

Is the above formula for bandwidth efficiency correct ?

But in simon haykin it is given that bandwidth efficiency is (log M )/2 log with base 2
