Analysis of a Software Bluetooth Modem Based on a DSP Implementation

Wireless modems are key part of mobile devices in adequate transmissions according to QoS. In order to adapt different wireless standard, future radios will need to be implemented on software form, Thanks to DSP and wireless technologies, today software modem radios for 2 and 2.5 G have already been implemented [11]. In Software Radio Defined project we aim to combine a several wireless communications protocols like HiperLan/2, GPS and Bluetooth, Here, we have analyzed a GFSK modem used in Bluetooth Technology. This work analyzes the performance of Bluetooth (GFSK) modulation and demodulation with an Integrate-and-dump decision algorithm. A simulation model was built to measure the performance of each of these stages. A key feature of this modem is that it is designed thinking in a future DSP implementation. The modem fulfills the Bluetooth specifications based on the IEEE 802.15 standard.
