Radio spectrum resources are becoming scarce with the increasing demand for multiple users wireless services. Hence, it is an important problem to increase the system potential capacity and coverage for wireless system in future. This paper aims at proposing a relay algorithm based on power control and SINR evaluation for two-hop OFDM cellular networks with fixed relay stations. This algorithm improves...
In time division-high speed packet access plus (TDHSPA+) system, multiple input multiple output (MIMO) technique is adopted to improve spectrum efficiency and transmission reliability. However, most current literature are focused on the large spacing antenna setup, which is impractical for user equipment (UE) because of the size limitation. Therefore, dual polarization antenna scheme is introduced...
