Abstract

IEEE 802.15.4b is an enhanced standard to the IEEE 802.15.4, addressing the needs for high-data rate transmission using 868 or 915 MHz band in the wireless personal area networks. This paper details a modulation and code mapping scheme designed specifically for the standard´s 868 MHz band that leads to efficient transmission and low implementation complexity. The code mapping scheme is called quadrature cyclic odd bit inversion length 16 or quad COBI-16. Among the scheme´s desirable properties is that the total phase rotation in the I/Q plane accumulates to O degree over the complete symbol. The scheme is tested in AWGN and Rayleigh fading channels. The results show that it conforms to all the stringent requirements defined by the standard
