MVSK provides the ability to realize enhanced data rates over a power-constrained channel at the same or greater distance as a lower-rate, narrowband link without the addition of extensive, signal processing or complex and expensive adaptive antenna capabilities. The benefits include practically jam-proof and interference-proof operation, resistance to many deleterious on-air propagation effects, extremely limited transmitter complexity, inherently error-correcting demodulation, and configurable band occupancy. The MVSK format achieves its many advantages through the unique integration of a number of advantageous RF techniques, including the use of fast and variable frequency-hopping, a dual-detection demodulation method, bare-carrier sense modulation, and intelligent baseband signal processing. In one example case, a 64-VSK link operating at 1.44 Mbps in the 4.4-4.9 GHz band with a 1E-5 BER would exhibit a worst-case 18 dB jamming margin. Compared to a traditional high-order modulation format like 64-QAM at the same data rate, MVSK shows a worst-case 34 dB jamming margin advantage and 5 dB transmitter power advantage, meaning longer range performance, especially in the congested real-world environment. These advantages are actually even much greater when the effects of intelligent MVSK baseband signal processing and the bare-carrier modulation approach are considered.
