摘要：大规模多输入多输出（MIMO）技术能够大幅度提升系统容量，降低不同用户间的干扰，但因其系统中信道维度高、信道估计和预编码算法复杂等因素，使得系统软硬件开销都会增大。将大规模MIMO系统的预编码算法分为数字、模拟和混合3种类型，并对3类预 ...

The drive to increase wireless data rates within the limited radio frequency (RF) spectrum is leading to radios with capabilities beyond a single-input single-output (SISO) topology. SISO radio ...

Emerging 4G mobile wireless radio technologies such as long term evolution (LTE) and WiMAX are focused on delivering higher levels of throughput. Multiple input, multiple output (MIMO) operation is ...

Oulunsalo, Finland—Cellphone test company Elektrobit Testing Ltd is rolling out a multi-channel emulator called the Propsim C8. The firm's latest new integrated version of Propsim is slated for ...
