Multi antenna transmitter beam formation devices and method of high data rate wide band packet conversion radio communication signal

摘要

Topic The multi antenna transmission beam formation devices of hight cost of production which actualizes the frequency dependant stressing in beam forming of the high data rate wide band packet conversion radio communication signal efficiency are offered low.SolutionsEach the plural high data rate wide band packet conversion radio communication signals to which N includes frequency (as for N correct integer) the multi antenna transmitter beams offers the device and the method of forming. The device by one execution example, (1) description above N concerning each of frequency doing the phase operation and stressing of the signal over M antennas, the transmission beam formation vessel which causes the phase operation M and not stressing straw raincoat frequency data and, (2) the phase operation above-mentioned M and has with high-speed opposite fourier transform unit (IFFT) M the not stressing straw raincoat frequency data is converted the digital output (as for M integer of 2 or more) M and (3) M transmission antennas which transmit the phase operation above-mentioned M and not stressing straw raincoat signal.
