Abstract |
|||
This project will implement a wireless headphone set and wireless microphone set that will take in analog audio input and transmit it to a receiver 30 meters away.
The project will consist of three parts: a wireless module, an audio compression module, and an A/D and D/A module. The A/D module will turn the analog audio into a digital bitstream. The wireless module will implement all facets of the wireless link between the transmitter and receiver, including the creation of data packets and the handshaking protocol needed to ensure that fewer packets are dropped while traveling through the wireless link. The compression and decompression module will take in an uncompressed digital audio signal, compress the bitstream, and introduce error-correction codes in the bitstream. Upon receiving data from the receiver, the decompression module will apply any error correction needed to the bitstream, and will pass it to the D/A converter module, which will interface with the headphone. |
