A 2/spl times/2 antennas Bluetooth system

This paper presents a new space-time FSK coding scheme suited for non coherent MIMO systems. These codes keep the natural advantages of the FSK modulations and achieve full diversity and high spectral efficiency. This coding scheme can be easily adapted to Bluetooth. We propose a 2/spl times/2 antennas Bluetooth FSK system that doubles the data rate and improves the performance.
