Basestation and method for receiving and processing signal in the basestation

The present invention relates to a method for simplifying the signal processing architecture of a base station in a base station that receives a signal into four branches by using two by two the second branch polarized antenna by each sector. The base station receives the signal with the first and second branch and the third and the fourth branch of the second polarized wave antenna in the first polarization antenna. A signal received by the second and fourth branches, respectively from the received signal the delay time so that the first and the offset signal and the distinction received in three branches. The following are received by the signal and the second branch to the first branch to receive summing the time-delayed signal, and is received by the second signal and the fourth branch to receive third branch, adding the time delayed signal. The summed signal is processed is separated into a signal that is distinguishable from the re-offset the base station modem processor. In the same way, without changing the modem processing unit of the base station you can implement a diversity using a second branch of two polarized antenna sector by sector. May also also the structure of the RF and IF signal processor simply.
