Cooperative communication exploits the broadcast nature of wireless channel and uses relay nodes to provide better reliability and higher data rates without increasing power and bandwidth. In this paper, the energy analysis of the asynchronous polarized cooperative (APC) scheme is performed. APC employs multiple antennas at the relay and destination nodes to achieve full duplex amplify-and-forward...
A Hybrid Antenna Selection (HAS), also called Soft Antenna Selection (SAS), method is basically implemented by a Linear Network (LN) which is located in RF domain of Multiple Input Multiple Output (MIMO) systems. In this paper, we evaluate the SAS-MIMO system, which is optimally tuned based on spatial multiplexing/diversity transmissions, in terms of receiver sensitivity issue. To this end, a SNR...
A novel space-time transmission technique that emulates Alamouti code with a single RF source is proposed in this paper. An orthogonal block of two BPSK signals is transmitted over a duration of two symbol periods by exciting one RF port of a two-element antenna system every symbol period while terminating the other port with its matching impedance. Besides the orthogonality of the signals, the array...
