Advanced Software Defined Radios for Wireless Communication with Improved Power Efficiency

Radio is one of the most common things that people use around the world. Marconi developed it in 1895 and since then there is no stop in its development, some of the domains like the cognitive radio and Software defined radio have seen great advancements in communication. In the following paper, we will explore the software defined radio and various techniques to implement the radio. When we talk about the Software defined radio every aspect of its operation is performed by controlling software SDR transmitter and Receiver which are used. In this paper, we will focus on the discussion to examine the reconfigurability and low power trade-offs. We will be building dedicated functional modules providing high performance at a high cost (Velcro approach explained below), versus parameterizable function blocks used in FPGA-based system development, and lastly dynamic partial reconfiguration which is the ability to reconfigured a portion of the FPGA while still remaining in operation.
