Based Msp430 Wireless Voice And Data Transmission System

There is a growing use of many small, portable, powerful communications equipment. So the traditional transmission cable being replaced by wireless communication. There are so many advantages compared to wireless transmission and cable transmission. First of all, no need to set up wires and cover a wide range, free from the geographical constraints. Secondly, it has high quality of voice and low error rate. Third, you can quickly find the reasons why it out of order and restore. Lastly it also has good security and confidentiality.First of all, This article describes two types of voice-data coding waveform coding and parametric coding, and they were introduced, by comparing the selected items as G.729 voice compression algorithms.Second, Analyzed the speech coding algorithm for the general principles, voice compression coding classification and different methods of implementation. In this paper, it proposed the design idea and implementation program of wireless voice transmission system; describe the project background and the application of value. According to the needs of the project suitable chip select.In many types of single-chip microcomputer to select this item fit MSP430 series ultra low-power single-chip microcomputer. With high programmability, high-performance, low-power, less peripheral device. Become the mainstream of voice processing products, audio processing chip TLV320AIC10. Specifically for the 433MHz ISM(industrial, scientific and medical) band job nRF401 transceiver chip.According to the various properties of the selected target chip design of the system hardware architecture and a voice compression coding algorithm.Thirdly, in this paper it description the IAR Embedded Workbench. It was a software manufacturerd by IAR , used for software development environment, then we can do program debug in IAR Embedded Workbench about function modularization.
