Subject: CMX7143 Modem Performance

This document contains details of tests to compare the performance of low deviation GFSK with 4FSK for applications seeking to maximise data rate in a given channel.

Both these modulations are available on the CMX7143 device.
For comparison purposes the chosen scenario is 9600bps in a 12.5kHz channel. The requirements of EN 300 113[2,3] are considered as part of the study.
