Al Altera FPGA for communication with FIR band pass filter has been analyzed and implemented in hardware and maximum allowable total power that interferes below than limit is adaptively calculated.
Latest technology requires increase in spectral efficiency by optimum utilization of the spectrum band with higher power efficiency. In this paper first, Altera FPGA for communication with FIR band pass filter has been analyzed and implemented in hardware and then maximum allowable total power that interferes below than limit is adaptively calculated. For power distribution, two power and capacity optimization algorithm; namely Water filling and Iterative water filling are used. The paper is also able to calculate and distribute power in different subcarrier for multiple nodes to maximize total system data rate or spectrum efficiency.
