Bluetooth Enhanced Data Rate Baseband Modeling and Implementation

Abstract [en]

The main issue of this thesis is making the behaviour model of Bluetooth EDR (enhanced data rate) baseband signal processing. This Bluetooth baseband project is part of the soft defined radio project at electrical engineering department, Linköping University.

In this project, both the basic rate and EDR model were built and simulated. The GFSK and π/4 DQPSK digital modulation and demodulation were implemented in C code. The BER was tested to evaluate the demodulation results. Furthermore, the error correction (FEC) and the error checking (HEC,CRC) were also implemented according to the Bluetooth standards. The CRC flag was detected to test the payload demodulation results.

Especially, GFSK and π/4 DQPSK specifications have to be combined with each other at sample rate of ADC.

Finally, the basic rate and EDR model were simulated to measure the BER and CRC performance.

From the simulation results, the receiver filter, synchronization and channel condition were three key points in this Bluetooth EDR system implementation.

So we get further understanding about the Bluetooth system specification and DSP implementation methods.
