Abstract
Multi-channel broadband re-configurable RF Front End for Software Defined Radio/Cognitive Radio. The RF front end helps improve spectrum sensing for better spectrum utilization. The RF front end comprising of multiple channels of reconfigurable transmitters and receivers, Tx/Rx switch, reference section, control section and power section is described. The RF front-end transceiver comprises of multiple channels and adapts its parameters based on the radio environment. The RF front end works on wide bandwidth and reconfigures its parameters.
Claims10
A multichannel broadband re-configurable RF front end system for software defined radios/cognitive radios with multiple channels operating on broad frequency range wherein each channel comprises of
- a RF transmitter for (Upconverting) converting baseband signal to a RF signal;
- a RF receiver for (Downconverting) converting said RF signal from antenna in to the baseband signal using double/dual conversion;
- a control and monitoring section with a controller for receiving sending signals for re-configuring said channel;
- a reference switching section for providing said reference frequency to frequency synthesizers in channels;
- a Transmit/Receiver switch to operate/perform a channel in TDD or FDD mode of operation and
- a power supply and conditioning circuit.
The multichannel broadband re-configurable RF front end system, wherein each transceiver channel is capable of performing transmitter function and/or receiver function.
The multichannel broadband re-configurable RF front end system, wherein one receiver of one transceiver channel is dedicated for sensing of spectrum holes if used for cognitive radio application.
The multichannel broadband re-configurable RF front end system, wherein the multiple channels increasing the reliability of the system. (like implementation of the MIMO).
