Improved beamforming code book for WiGig using Maximal Ratio Combining

IEEE 802.11ad standard, so called WiGig has been defined due to the increasing market demands for high data rate communications. The standard was approved at 60 GHz band employing a beam formation to mitigate interference signal. However, a signal loss is introduced at the intersection of two adjacent beams when employing original beamforming codebook, hence the systems provide low BER. Therefore, this paper proposes an extra codebook to avoid the signal drop at direction of beam intersection. The computer simulation reveals lower BER when employing the proposed beamforming codebook.
