| Abstract: | To resolve the limited energy problem of the sensor network nodes in the marine environment monitoring system,the differential encoding is introduced to reduce the bit error rate in the data transmission.A binary tree compressed encoding algorithm is presented.This algorithm which compresses the original data to save energy has some evident advantages,such as easy programming,less computation and convenient realization on hardware.And it achieves a satisfactory result in the mathematical calculations and Matlab simulation. |
