Abstract : Software Defined Radio is an all new technology being developed in the 21st century. Over a past couple of decades many Mobile communication standards have evolved and even today researches are going to develop new standards. Different standards of Mobile communication use different type of hardware circuitry. The existing mobile communication standards are primarily regional and not global. So efforts are going on to develop systems which can support multiple mobile communication standards using same hardware but swapping the software. The main aim of this paper is to develop a model of a Software defined Radio using SIMULINK tool to implement the IEEE 802.11 standard and the Bluetooth standard. The main aim of this paper is to build various protocols for WLAN and the Bluetooth standards and to demonstrate their functionality. This includes implementation of IEEE 802.11a standard for the WLAN and basic core protocols for the Bluetooth. According to the IEEE 802.11a standard out of the various transmission modes the basic transmission mode (BPSK with 6Mbps transmission speed) was implemented. For forward error correction half convolution codes are used. The communication channel is assumed to be flat fading channel where the transmitted sub carrier undergoes flat fading. The ideal channel model for this type of channel is chosen as Nakagami channel. Regarding the Bluetooth technology all the core protocols of Bluetooth are implemented and the type of modulation is Gaussian phase shift keying and frequency hopping spread spectrum.
