Description: Ajey, S., B. Srivalli, et al. (2010). On performance of MIMO-OFDM based LTE systems. Wireless Communication and Sensor Computing, 2010. ICWCSC 2010. International Conference on.
4G wireless systems predominately employ multiple input multiple output (MIMO) with an orthogonal frequency division multiplexing (OFDM) system. Like other 4G systems long term evolution (LTE) also employs MIMO-OFDM physical layer. MIMO helps in increasing the throughput whereas OFDM converts a frequency selective fading channel to multiple flat fading sub-channels facilitating easy equalization. It is proposed that LTE system should mandatorily support 2Ã — 2 MIMO setup. Our paper focuses on the performance of such a LTE system with two transmit antennas and two receive antennas in a frequency selective fading environment.

Description: MIMO-OFDM雷达波束形成及优化。首先，MIMO-OFDM雷达和OFDM-MIMO雷达的定义在不同的期刊是不同的。这里MIMO-OFDM雷达的定义同IET期刊，即发射阵列应用频率分集。MIMO-OFDM雷达同时使用了频率分集和波形分集，当发射阵列阵元间距是接收阵列阵元间距的N倍时，虚拟孔径最大，这时波束最窄，空域分辨力最高。(Beamforming and its optimization of MIMO-OFDM radar, the definition of MIMO-OFDM radar and OFDM-MIMO radar in different journal are fifferent. the MIMO-OFDM radar is equal to IET journal, that is transmitting end is frequency diverse array. Both frequency diversity and waveforms diversity are used in MIMO-OFDM radar, while interelement range in transmitting end is N times of receiving end, the virtual aperture is maximum, and spatial resolution is maximum.)

Description: 因此，通过在数字预编码器上实施正交约束，然后提出低复杂度的AltMin算法。 此外，对于部分连接的结构，AltMin算法也是在半定理松弛的帮助下开发的。为了实际实施，所提出的AltMin算法进一步扩展到具有正交频分复用调制的宽带设置。 仿真结果将证明所提出的AltMin算法相对于现有的混合预编码算法具有显着的性能增益。 此外，基于所提出的算法，两种混合预编码结构之间的仿真比较将提供有价值的设计见解。(Therefore, by implementing orthogonal constraints on the digital precoder, a low complexity AltMin algorithm is proposed. In addition, for partially connected structures, the AltMin algorithm is also developed with the help of the relaxation of semi theorems. For practical implementation, the proposed AltMin algorithm is further extended to broadband settings with orthogonal frequency division multiplexing modulation. Simulation results show that the proposed AltMin algorithm has significant performance gains compared with the existing hybrid precoding algorithm. Furthermore, based on the proposed algorithm, the simulation comparison between the two hybrid precoding structures will provide valuable design insights.)
