An architecture for a frequency hopped spread-spectrum transmitter-receiver in an advanced tactical data link packet switched network that ensures optimal Statistical Priority-based Media Access (SPMA) performance, enables more efficient packing of hop channels in a given allocated bandwidth and counteracts hostile jamming. The transmitter-receiver supports a scalable symbol rate mode that reduces the symbol rate in the time domain and decreases the bandwidth in the frequency domain, over a predetermined prior value. A transceiver according to the present architecture is able to statically or dynamically scale the symbol rate of transmissions, operate in burst mode and change the hop set. In one embodiment the transceiver is part of a Software Defined Radio (SDR).
