A method including receiving, by an antenna combiner of a wireless communication system, a set of Random Access Channel (RACH) sequences of a first RACH signal from a first antenna and a set of RACH sequences of a second RACH signal from a second antenna. The method further including selecting, by the antenna combiner, each RACH sequence of the set of RACH sequences of a selected RACH signal from a selected antenna that has a best Signal to Interference plus Noise Ratio (SINR) from each RACH sequence of the set of RACH sequences of the first RACH signal from the first antenna that has a first SINR and each RACH sequence of the set of RACH sequences of the second RACH signal from the second antenna that has a second SINR.
