Synopsis

Comparing FM and PCM-FS systems to help you design reliable links.

This technical report evaluates how multiple frequency-shift-keying (FSK) and PCM-FS schemes perform in real-world radio links. It explains how element and symbol error rates relate to signal-to-noise characteristics, and how different demodulation approaches affect performance. The work also frames the comparison between band-dividing FM and PCM-FS systems through practical design criteria.

Readers will gain a clear view of how system parameters—such as the number of frequencies, quantizing levels, and coding base—influence the intrinsic signal-to-noise ratio, thresholds, and overall efficiency under various criteria.

• How increasing the number of frequencies in FSK affects error rates and threshold behavior.
• How band-dividing FM demodulators compare with PCM-FS under minimum-bandwidth, minimum-power, and channel-capacity criteria.
• What intrinsic SNR means in practice and how it changes with modulation index and quantizing levels.
• How to choose between FM and PCM-FS for a given bandwidth or power constraint.

Ideal for engineers, researchers, and students seeking practical guidance on choosing and tuning modulation schemes for reliable communications.
