Abstract :
The second generation GTE Airfone Public Correspondence System, GenStar, will employ digital transmission to improve performance, increase service offerings and provide for future capacity enhancements. With 6 kHz channel spacing and an aggressive throughput target, high-level modulation schemes were considered early in the system design. By analysis and measurement, 16 QAM was determined to be a suitable candidate for this application. The authors describe the assessment of 16 QAM as a transmission technique for the commercial air-to-ground transmission channel
