Communication Equipment, namely headsets for facilitating communications with and among aged hearing challenged persons or among persons in a noisy environment.
|WHAT DID GADGEON DO?||PLATFORMS/TOOLS/TECHNOLOGIES USED|
|1) Architecture of the product for Bluetooth connectivity, digital audio processing and mixing.||Requirements Gathering & Analysis, Uses cases, Architecture development, identification of functional components.|
|2) Hardware design, prototyping, boardbring up for Bluetooth module interface to controller and I2S interface for mixing and streaming.||Cadence allegro, fully digital design for reduced noise.|
|3) Embedded bootloader and firmware for Bluetooth pairing with
headsets, audio streaming, mixing and firmware update over Bluetooth.
|STM32 libraries, Keil, FreeRTOS, COTS Bluetooth module, STA309 Mixer from ST.
STA309 driver for mixing of audio streams, I2S interface configuration
Bootloader customization for firmware upgrade.
|4) Created algorithms for noise cancellation using adaptive LMS
algorithm and blind signal separation algorithms for demonstration.
|Octave DSP development platform, TMS320C6746, TI Code Composer Studio|
