  1. 1. Performance evaluation of interleaving techniques for IEEE 802.15.4 transmissions

    University essay from Mittuniversitetet/Avdelningen för informations- och kommunikationssystem; Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

    Author : Jiahuan Lei; Qingbi Liao; [2014]
    Keywords : interleaving; Matlab; Reed-Solomon; TinyOS; WSN; FEC; MicaZ;

    Abstract : In the wireless sensor network, the WLAN interference, multi-path fading andattenuation are the main reason for packets’ corruption. Forward errorcorrection is one of the methods for error mitigation. Many coding methods aredesigned to improve the reliability of wireless channel. READ MORE
