Abstract:In our software-defined radio project we aim at combining
two standards: Bluetooth and HiperLAN/2. The Hiper-
LAN/2 receiver requires the most computation power in comparison with Bluetooth. We choose to use this computational power also for Bluetooth and look for more advanced demodulation algorithms such as a Maximum A posteriori Probability (MAP) receiver. This paper discusses a simplified MAP receiver for Bluetooth GFSK signals. The Laurent decomposition provides an orthogonal vector space for the MAP receiver. As the first Laurent waveform contains
the most energy we have used only this waveform for our
(simplified) MAP receiver. This receiver requires a Eb
N0 of about 11 dB for a BER of 10¡3, required by the Bluetooth standard. This value is about 6 dB better than single bit demodulators. This performance will only be met if the receiver has exact knowledge of the modulation index.
