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...
Similar to its frequency division duplex (FDD) counterpart, there is currently great interest in introducing multiple-input multiple-output (MIMO) antenna technique into time division-synchronized code division multiple access (TD-SCDMA) high-speed packet access evolution (HSPA+) system within 3GPP. To this end, per-antenna rate control (PARC), selective-PARC (S-PARC) and dual-stream transmit antenna...
Installing multiple antennas at user equipments (UEs) may pose great challenges. In virtual multiple-input multiple-output (MIMO) concept, multiple single-antenna UEs can be grouped to transmit signals at the same time. Their signals can be separated at the base station (BS) by the same methods already used in conventional point-to-point MIMO scenarios. An important problem in virtual MIMO application...
