Product: Develop a SDK/library which will enable data transmission between 2 devices using inaudible ultrasound. PART 1 - Design algorithm for the product - on PC, using MATLAB maybe? Platform: Am neutral on this. Developer can use what he is most comfortable with, but please be aware, that the end goal of the product is to be emulated on a smartphone, as a embeddable SDK. So, resource requirements used to achieve result have to be comparable to what is available in above average smartphones. PART 2 - Based on Algorithm, develop a SDK/Library that can be embedeed into either a iOS or Android app, enabling the app to transmit and/or receive data using audio. Target specs 1. Full duplex (both devices transmit and receive at the same time) 2. Baud rate of 250 bps each way 3. Elaborate noise reduction and necessary compensation 4. Advanced error correction 5. Prefer to be Inaudible to humans, but has be frequency that can be ?picked up?/emitted by speaker/mic of most smartphones. Usable...
