Detailed Solution
Download Solution PDFBandwidth efficiency:
Spectral efficiency usually is expressed as “bits per second per Hertz,” or "bits/s/Hz".
In other words, it can be defined as the net data rate in bits per second (bps) divided by the bandwidth in hertz.
Bandwidth efficiency is given as:
\(\eta=\frac{R_b}{BW}\)
Note:
The bandwidth efficiency of M-ary PSK is
\(\eta= \frac{{{R_b}}}{BW}\)
\(BW = \frac{{2{R_b}}}{{{{\log }_2}M}}\)
