Rhyme Test Performance of ACSB (Amplitude Compandored Single Sideband), Narrowband, and FM Radios

摘要

In this fifth of nine reports concerning spectrum efficient technologies, amplitude compandored single sideband (ACSB) radios and narrowband (NB) radios using amplitude and frequency compandors are compared with conventional frequency modulation (FM) radios by using the Dynastat Corporation's Diagnostic Rhyme Test (DRT). This test provides a measure of the intelligibility of a received signal based on listener identification of initial consonant sounds of single syllable words. The test also provides subjective ratings of several aspects of signal quality based on listeners' personal preference.
