   Sammanfattning : High Altitude Platform Stations (HAPs) are communication facilities situated at an altitude of 17 to 30 km and at a specified, nominal, fixed point relative to the Earth. They are mostly solar-powered, unmanned, and remotely-operated. LÄS MER

3. 2. Bluetooth Enhanced Data Rate Baseband Modeling and Implementation

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Lei Zou; [2006]
   Nyckelord :Bluetooth; Baseband; GFSK; π 4 DQPSK; BER; CRC; Filters; Synchronization; Channel; DSP;

   Sammanfattning : 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. LÄS MER
