Multiple Antenna Techniques in 4G wireless communication.
With multiple antennas we can achieve significant improvements in following performance parameters.
1. Higher data rates over the air interface.
2. Farther signal penetration and improved coverage.
3. Lower signal losses due to reduced interference.
4. Lower power consumption.
5. Support of more users with better quality and spectral efficiency.
Multiple antenna’s are in order of two:2x, 4x or 8x.
Multiple antenna core functionality.
The core functionality of all multiple antenna techniques is to send the same signal over the air on multiple channels. Chances of signal getting corrupted on multiple channels is very limited and signal can be recovered easily at receiver. These techniques also focuses on sending the signal energy in one direction rather than broadcasting.
