LFM
针对传统线性调频(LFM)信号参数估计算法中复杂的搜索和计算问题,提出了一种不需要参数搜索的快速
LFM信号参数估计算法。该算法先用希尔伯特变换估计LFM信号瞬时相位,再用二次相位函数拟合LFM信号瞬
时相位从而得到初始频率和调频斜率的估计(The traditional linear frequency modulation (LFM) signal parameter estimation algorithms and computational complexity of the search problem, we propose a fast search without LFM signal parameter estimation algorithm. The algorithm first estimated with the Hilbert transform of LFM signal instantaneous phase, and then the second phase of LFM signal instantaneous phase function fitting to obtain the initial estimates of the frequency and chirp rate)

4x4mimo
A 2x2 multiple-input multiple-output (MIMO) architecture
using dual-polarized antennas (DPAs) is considered
with orthogonal frequency division multiplexing (OFDM). The
performance of DPAs is evaluated for adaptive polarization
(AP) transmission techniques in time-varying multipath channels
impaired by polarization mode dispersion (PMD) and
polarization-dependent loss (PDL). AP transmission techniques
considered include power gain maximization, polarization dispersion
minimization for interference avoidance, polarization
multiplexing with waterfilling, and a suboptimal multiplexing
strategy that enables direct recovery of the polarization multiplexed
streams, thereby simplifying the design of the receiver.
Measured time-varying dual-polarized channel realizations from
mobile-to-mobile experiments are used to estimate the capacity,
diversity, and interference avoidance performance of the adaptive
approaches.
