Beamforming is being used in sensor networks to enhance its communication range.The sensors in networks use their own clock adjustment for distributed beamforming by coordinating with other sensors. For this, the Channel State Information(CSI) is required. Since the CSI is not available at the transmitter side, the Channel Phase tracking is used. A novel bisection based phase tracking method is proposed...
Beam forming is a technique designed for antenna an array in which phase of each antenna element is adjusted such that the resultant waves are coherently added to get maximum signal strength at the desired direction. This technique has been applied to sensors recently. Since the sensors are randomly distributed, the randomness introduces deviation in position of sensors from ideal linear array. The...
