Executive Summary

The necessity of high data rates wireless communication becomes important for the end-user, especially to support high mobility lifestyle "Always get connected", and demand for the multimedia communication, such as the video phone, live streaming, online gaming, and the Internet. Since wireless communication systems need to deal with multiband and multimode operations on complex signals many-a-times, the efficient phase and magnitude extraction is always needed. This paper presents an architecture for the efficient Rectangular to Polar Conversion (RPC) for these multiband and multimode wireless communications using fully parallel CORDIC, a Linear Convergence Algorithm. The architecture was synthesized with ISE 10.1 software and was implemented in a Xilinx FPGA device achieving better performance than the previous LUT-based approaches.
