AI Technical Summary

Problems solved by technology

Concerns about power consumption are further exacerbated by the high-power amplifiers used in conventional beam-hopping PS-TDMA architectures, since the power supplies to the high-power amplifiers cannot be switched on and off at typical TDMA frame slew rates, and, even Must remain on when no RF signal is present

Abstract

A communication system including at least one first TDMA high speed switch having a first switch output, a FDMA channelizer, configured to receive an input RF signal from the at least one first TDMA high speed switch, at least one matrix power amplifier having at least one input and at least one output, and at least one second TDMA high speed switch having a second switch input coupled to a respective one of at least one channelizer output and at least one second switch output coupled to a corresponding input of the at least one matrix power amplifier, the at least one second TDMA high speed switch being configured to receive an output RF signal from the FDMA channelizer and transmit the output RF signal to a selected input of the at least one matrix power amplifier, wherein each predetermined output is coupled to a corresponding antenna beam.

Description

technical field [0001] The present invention relates to a communication system and method for communication, and more particularly, to a novel FDMA / TDMA architecture using channelizers and matrix power amplifiers. Background technique [0002] Typically, in the field of telecommunications, communication transmissions are facilitated through the use of communication platforms (eg, relay stations). These communications platforms include manned and unmanned, manned and unmanned aircraft (UAV) and lighter-than-air (LTA) platforms that pass over or hover over areas of territorial coverage, ranging from average altitudes into any orbit Any vehicle for communication satellites (not just Earth's, but any celestial body such as the Moon or Mars). Typically, communication platforms function on the bent pipe principle, where they receive signals from the ground via receive antenna beams and return signals to Earth via transmit antenna beams using only amplification and conversion from...
