Constant improvements in techniques applied to different radio communication system stages, including coding, modulation, synchronization and security, make any implementation quickly obsolete. On the other hand, different communication standards used among military and public safety agencies make difficult the necessary interoperability. These reasons force users to replace equipment frequently, increasing cost and implementation time. Software Defined Radios (SDRs), partly implemented in software, can solve these problems, making full use of programmable modules. This thesis presents an implementation of the necessary algorithms that solve the synchronization requirements of IEEE 802.11a WLAN receivers. This is a continuation of a previous thesis effort, where the post-synchronization steps of the receiver were addressed. The software utilized for this purpose is the Open Source SCA Implementation::Embedded (OSSIE), developed by Virginia Tech. Each algorithm was created as a different component, allowing reuse and modularity for the development of future waveforms.
