A new WSN transceiver based on DWPT for WBAN applications

Body networks type WBAN (Wireless Body Area Network) are beginning to take a major interest in last years. Generally, modern transmission face three major challenges: energy management for transmission, increase throughput and noise immunity. The use of broadband systems helped answer constraints of modern transmission system, it has questioned the use of complex and cumbersome systems: CDMA and OFDM. This has prompted the search for technical lower layers: physical and MAC. In this paper, we present a new form of communication for WBAN applications based on Discrete Wavelet Packet Transform (DWPT) in transmitter and Inverse Discrete Wavelet Packet Transform (IDWPT) in receiver. We will propose a new form of many-to-one transceiver for medical applications.
