Abstract

A software defined radio system is described. The software defined radio comprises a modem bank at least partially defined by software running on a processor. The software defined radio also comprises an antenna group translator coupled to the modem bank. The software defined radio also comprises at least one antenna coupled to the antenna group translator. Further, the software defined radio comprises a program stored in a memory and running on the processor. The program is configured to generate a test signal to be leaked by the first of the at least two channels and to be received by the second of the two channels. The program is configured to automatically and autonomously verify the availability of a function of one of the at least two channels and determine the integrity of the function of the one of the at least two channels.

Claims

1. A method of providing at least one of availability verification and integrity checking for receiving using a software defined radio (SDR), comprising:

reconfiguring at least one radio channel, the at least one radio channel each having at least one radio function associated therewith;

sending a test signal using a second radio channel;

receiving the test signal by the at least one radio channel;

checking for a test characteristic of the test signal;

making the at least one radio channel and at least one radio function available for use;

wherein the test signal includes a test signal identifier;

wherein the second channel is a spare channel;

wherein the signal is sent over a leaky transmitter;

wherein the SDR is part of a communication, navigation and surveillance (CNS) System; and

wherein the SDR is an avionics SDR.

2. A method of providing at least one of availability verification and integrity checking for transmitting using a software defined radio, comprising:

reconfiguring at least one radio channel, the at least one radio channel each having at least one radio function associated therewith;

sending a test signal using the at least one radio channel;

receiving the test signal by a second radio channel;

checking for a test characteristic of the test signal after being received by the at least one radio channel;

making the at least one radio channel and at least one radio function available for use; and

wherein the test signal includes a test signal identifier wherein the second channel is a spare channel wherein the signal is sent over a leaky transmitter wherein the SDR is a ground-based military radio.
