Middle modulation error display method for use in multi-signal carrier system, involves computing squarely weighted average value of amplitude of all ideal signaling status of modulated carrier

摘要

The square of error vector is computed for every current modulation symbol (i) of every individual carrier (k) of multi-signal carrier. The computed value is evaluated with value of storage elements of memory. The squarely weighted average value of amplitude of all ideal signaling status of modulated carrier is computed for estimating middle modulation error for every carrier and displayed graphically. The middle modulation error value computed for every carrier is displayed graphically by an ordinate value with number of carriers represented as abscissa. An Independent claim is also included for maximum modulation error display method.
