	ABSTRACT="In digital agriculture, the cognitive radio technology is being envisaged
	as solution to spectral shortage problems by allowing agricultural
	cognitive users to co-exist with non-cognitive users in the same spectrum
	on the field. Cognitive radios increase system capacity and spectral
	efficiency by sensing the spectrum and adapting the transmission
	parameters. This design requires a robust, adaptable and flexible physical
	layer to support cognitive radio functionality. In this paper, a novel
	physical layer architecture for cognitive radio based on cognition,
	cooperation, and cognitive interference avoidance has been developed by
	using power control for digital agriculture applications. The design is
	based on sensing of spectrum usage, detecting the message/spreading code of
	noncognitive users, cognitive relaying, cooperation, and cognition of
	channel parameters. Moreover, the power and rate allocation, ergodic, and
	outage capacity formulas are also presented."
