Abstract
Antenna arrays are widely employed in communication systems, because the performance improvements over single antenna systems. The noise in multiple antennas may be statistically dependent from antenna to antenna and may be non-Gaussian. In this paper an efficient estimation of two-dimensional version Middleton's Class A noise model parameters is derived based on Markov Chain Monte Carlo (MCMC). This estimator can estimate five-parameter and hidden states for two-dimensional Class A noise model simultaneously. Simulation of this estimator indicates that this considered estimator is fast converges and low complexity for small data samples.
天线阵列由于其性能优于单天线系统,在通信系统中得到了广泛的应用。多个天线中的噪声可能在统计上依赖于天线之间的噪声,并且可能是非高斯的。本文基于马尔可夫链蒙特卡罗(Markov Chain Monte Carlo, MCMC)导出了二维版本米德尔顿A类噪声模型参数的有效估计。该估计器可以同时估计二维A类噪声模型的五参数状态和隐藏状态。仿真结果表明,该估计器对于小样本数据收敛速度快,复杂度低。
