A novel data compression approach to reduce string size for PLCC based DAS

MATLAB based DCSK communication scheme developed for PLCC based DAS requires longer time of execution at receiving end particularly with longer strings. In order to avoid the problem, basic arithmetic coding based lossless data compression method is proposed which can reduce the string size of string and consequently improve the performance of the system significantly. As conventional DAS deals mostly with integer values only, the algorithm is developed for integer string only. But this proposed method can be modified suitably and can be implemented for character strings successfully.
