Abstract
A system and method for providing audio communications for a simulation system. A computer network has a server in data communication with client systems. The server receives audio from a transmitting client. It then executes transceiver models and impairment models, which inject effects of audio communications media and equipment into sampled audio data. The server then delivers the “impaired” audio to a receiving client.
Claims30
A method for providing simulated audio communications, which simulate an RF transmission using a selected type of RF transceiver and a selected type of RF transmission medium, to a simulation system, comprising the steps of:
- linking as a data network, a server and two or more client systems;
- storing at least one transceiver model, accessible by the server, wherein the transceiver model stores data representing audible transceiver effects of the selected RF transceiver;
- storing at least one impairment model, accessible by the server, wherein the impairment model stores data representing audible transmission effects of the selected RF transmission medium;
- sampling voice input at a first client system, resulting in sampled voice data;
- transmitting the sampled voice data to the server;
- using the server to add additional audio data to the sampled voice data, by applying at least one transceiver model and at least one impairment model, wherein the transceiver model injects transceiver effects into the sampled voice data and the impairment model injects transmission effects into the sampled voice data, thereby resulting in processed audio data;
- wherein one of the transmission effects is noise due to the transmission medium;
- wherein at least one of the transceiver effects operates to limit amplitude of the audio data due to transceiver sensitivity;
- transmitting the processed audio data to a second client system.
A system for providing simulated audio communications, which simulate an RF transmission using a selected type of RF transceiver and a selected type of RF transmission medium, comprising:
- a data network having a server and two or more client systems;
- wherein a first client system is configured to sample voice input, resulting in sampled voice data, and to transmit the sampled voice data to the server;
- a database for storing at least one transceiver model, accessible by the server, wherein the transceiver model stores data representing audible transceiver effects of the selected RF transceiver;
- and for storing at least one impairment model, accessible by the server, wherein the impairment model stores data representing audible transmission effects of the selected RF transmission medium;
- wherein the server is configured to add additional audio data to the sampled voice data, by applying at least one transceiver model and at least one impairment model, wherein the transceiver model injects radio transceiver effects into the sampled voice data and the impairment model injects radio transmission effects into the sampled voice data, thereby resulting in processed audio data;
- and to transmit the processed audio data to a second client system;
- wherein at least one of the radio transmission effects is noise due to the transmission medium;
- wherein at least one of the transceiver effects operates to limit amplitude of the audio data due to transceiver sensitivity;
- wherein the second client system is configured to receive the processed audio data.
