Combined beamforming-diversity wireless fading channel de-modulator using sub-array grouped adaptive array antennas, portable telecommunication receiving system comprising it and method thereof

Sub-array using a grouping adapted array antenna beamforming and diversity radio fading channel, a demodulator for providing a gain, a mobile communication receiver system and method having the same are disclosed. The wireless fading channel demodulator, the sub-beam formed by combining and diversity gain, by using the array grouping the adapted array antenna, thereby eliminating the interference of other users in a wireless terminal station that enters a fading channel environment, a different angle. Therefore, robust and sub fading - may be obtained with high SINR by the beam formation properties is obtained in each of the array grouping the antenna, a number of effects that can be obtained with high SINR, even if less than the number of the terminal station user of an antenna . These wireless fading channel, the demodulator, can be used in any system for receiving a mobile communication information, such as a base station or a terminal station.
