    In this decade, WBAN plays vital role in health care monitoring environment. It has been used more intensively in wider applications. This paper proposes error control coding applied to WBAN. LDPC codes with the block size of 255 bytes are particularly of interest. Patterned information such as MIT-BIH's arrhythmia datasets extracted from Electrocardiography (ECG) of the patients who encountered heart disease. To measure the system performance, random data are also examined. The system was simulated on Rician channel where severe noise are quite nature to WBAN compared to AWGN channel. Rician channel with some K-factors was investigated. The obtained result shows that both patterned data and random data can be recovered well when Eb/N0 equals 3 dB and above. While the code rates were made varied from 0.50 to 0.75, we can obtain the gain of 3 dB, 5 dB, and 6 dB respectively.
