Abstract: An asymmetric power amplifier includes: an input port for receiving a multi carrier signal including a first subcarrier and a second subcarrier; a first tunable analog filter for filtering the received multi carrier signal into a first signal of the first subcarrier; a second tunable analog filter for filtering the received multi carrier signal into a second signal of the second subcarrier; an amplifier for amplifying the first signal of the first subcarrier; a power amplifier for power amplifying the second signal of the second subcarrier; a combiner for power combining the amplified first signal and the amplified second signal to form a power combined multi carrier signal; and an output port for outputting the power combined multi carrier signal to be transmitted by a transmitter.

Abstract: Electronic devices and a method of providing electronic warfare (EW) data in an encapsulated architecture in a vehicle are generally described. Emitters targeting the vehicle during a mission may be detected and an observable history of each emitter obtained as a function of time. Properties of each emitter may be both inferred based on the observable history and extracted from locally-stored pre-mission intelligence. The emitter properties, as well as current and historical state and threat level of the emitter and effectiveness of various countermeasures may be stored in an adaptive radar model (ARM) for the emitter. Each emitter may have its own ARM. The ARM may be used to take appropriate countermeasures for a particular emitter, based on the emitter alone or taking into account all of the emitters.

Abstract: Radio-frequency (RF) signal analysis includes slow-time signal processing and fast-time signal processing. Incoming RF pulses are captured according to a resource scheduling configuration. The fast-time signal processing is to prioritize the captured RF pulses for slow-time signal processing based on dynamic pulse-grading criteria. The slow-time signal processing is to perform relevance evaluation of the prioritized RF pulses, and to adjust the dynamic pulse-grading criteria and the resource scheduling configuration based on the relevance evaluation.

Abstract: Rate domain numerical processing comprises receiving an input serial data stream on a single input wire in which a multi-valued number is represented as a rate of pulse events comprising pulses, null pulses or a combination thereof. The rate of pulse events in an output serial data stream is varied in accordance with an operand to perform a multi-valued arithmetic operation selected from multiplication, division, addition and subtraction or a combination thereof. The rate may be varied by scaling the rate by an operand, which may be implemented using a count and compare circuit topology. The output serial data stream is output on a single output wire. The rate domain operations, specifically multiplication and division are accomplished without the resource & power intensive binary multiplier and binary divisions circuits. The operations are implemented using simple registers, adders, accumulators, counters, comparators, and basic logic, which is far more SWaP-C efficient.

Abstract: A method for allocating system resources includes receiving, by a processor, an assignment list that includes a first assignment and a second assignment, each assignment is assigned a priority and includes tasks associated with each assignment, assigning each assignment to a system resource according to the assigned priority of each assignment, populating a tree for the system resource, the tree including each assignment assigned to the system resource ordered by the relative priority of the assignments, generating task roots associated with each task associated with each assignment in the tree, associating each task root with a task score, defining a first system resource root that includes the task roots having the lowest task scores, calculating a first system resource root score as a function of the task scores of the first system resource root, and saving the first system resource root as the current best estimate system resource root.
