Adaptive Transmissions of Rate and Power for Energy Saving In DPSK-OFDM Based Base Stations



Digital signal processing came long way from wire-based optical fiber communication to wireless-based high rate supported communication models.. Mobile communication has become part of daily life and mobile usage has witness immense growth results in high energy consumption which remains concerned area in resource management. Previously we have base-station antennas those are having fixed power allocation alogorithms.But due to fixed power allocation algorithm power is not utilized in efficient way as user are increasing or decreasing with time. These observations are conducted by ICT. Green communication technology is proposed in this paper for effectively controlling the data rate and power consumption to save the energy. The problem of energy minimization at BS transceivers subject to certain quality-of-service and fairness requirements for all users is addressed in this work based on communication activities in downlink transmissions of the BS with orthogonal frequency-division multiple access-based multi CCs are considered.  Experimental results reveal that proposed method yields better results than traditional algorithms.
