Research on the Joint Source Channel Coding of Wireless Sensor Network

With the development and wide application of multimedia technology it has increased image, sound and the transmission of other signal to a great extent which is a great challenge for the wireless communication, especially for wireless sensor networks. Wireless sensor network has the flexibility, adaptability, easy construction and other characteristics, in order to guarantee the transmission quality of the image in the channel, at the same time it needs to optimal encoding for the source and channel. Based on a wireless sensor network, this paper proposes a joint source and channel coding algorithm, and the use of FPGA technology builds the source channel coding system; the experiments prove that the proposed new algorithm can improve the source and channel coding efficiency, and it has anti-interference ability and good robustness.
