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.

First claim

We claim:

1. A system for at least one of software defined radios and cognitive radios, said system comprising:
a multichannel broadband re-configurable RF front end for operating a plurality of transceiver channels of said software defined radios and cognitive radios on a broad frequency range, wherein each transceiver channel comprises,
an RF transmitter for upconverting a baseband signal to an RF signal;
an RF receiver for downconverting said RF signal from an antenna in to…
