Hi
i have to simulate the algorithm of a paper "A Real-Time ECG Data Compression and Transmission Algorithm for an e-Health Device". one part in this article is window filter after DCT.The author explains this phase : "In order to implement a high compression ratio, the DCT window size,which is chosen to be proportional to the DCT result, is adjusted from 15% to 100%."
With no window size, the result is OK. But i do not know the meaning of DCT window size and how can i do it in matlab. i use dct function in matlab for DCT.
Please help me
