Abstract
Cellular telephony and wireless Internet access are creating a growing demand for high quality wireless communications. Unfortunately, the current wireless communication infrastructure is not fully equipped to offer these unprecedented data rates and quality of service. The major obstacles include limited bandwidth availability, limited transmit power, and fluctuations in signal strength which are intrinsic to the wireless channel. Future wireless standards are relying on innovative core technologies, such as massive multiple-input multiple-output (MIMO) communications and small cell base stations (SBSs), are expected to see widespread use anddeployment. to overcome these problems.
One potential solution to address these issues is to overlay small cell access points with macro cell base stations as a mean to provide higher network capacity and better network coverage. The major problem, which met the small cells densification, is the strong interference power from the adjacent macro cells. Hence, the aim of this thesis is focused on the investigation and analysis of low complexity, multiple antenna techniques and approaches to enable energy efficient transmission and reception schemes applicable to small cell base stations. A new space-time block code is proposed, which can be used by outdoor small cell BSs. The small cells are equipped with two antennas and transmit three symbols via three time slots. The new code can cancel the overall interference that affects the small cell data transmission.
