Abstract

An improved efficiency technique for modified duobinary (class-IV) partial-response signaling (PRS) above Nyquist rate transmission is introduced. By using this technique, an increase of 4% or more above the Nyquist rate with class-IV 15-level PRS/225-QPRS, i. e. , a spectral efficiency of 6. 24 b/s/Hz or more, can be achieved by symbol-by-symbol detection with a small degradation, which is not feasible with the conventional method. It is further shown that with 4% increase in spectral efficiency for the improved class-IV 225-QPRS, an addition 3% of the Nyquist bandwidth can be carved out for a service channel.
