Body Area Network (BAN) with OFDM Enhances Data Transmission in Wireless Health Monitoring Systems (WHMS)

摘要

Advanced wireless technologies are rising our hopes to meet the demands in health and communication. After 3G, the new orthogonal FDM (OFDM) is bringing new facility in terms of secured data transmission over a network without multipath fading. Biomedical data which are generally bulky and need a very reliable and efficient data communication network can use this technique without failure, thus meeting our goal to develop an advanced WHMS enabled society. Recently, orthogonal frequency-division multiplexing (OFDM) is being widely used as a means of data communication. OFDM system is capable of error free, high speed wireless transmission with almost zero Inter-symbol interference. Here, we present a way to design an OFDM network using TMS320C6713 DSK and provide a way to implement UART using McBSP and ER900TRS transceiver. In this paper we also analyze the performance of different codes used in code-division-multiple-access (CDMA) system. The performance of the system is evaluated using experimental data obtained from the design and implementation on Texas Instrument's TMS320C6713 DSK kit.
