摘　　要：二维复指数信号广泛应用于许多实际场合,本文利用复随机信号处理方法研究其最小二乘估计的渐近性能。D.Kundu等人(1996)是将复信号表为实部和虚部来讨论的,因而非常繁琐。用复信号处理方法将可使讨论大大简化。By use of the approach of complex random signal processing, the asymptotic statistical properties of the least square estimates of 2-D exponential signals are studied. In doing so it is found that the representation is considerably more intuitive, and is analytically more tractable.

关 键 词：二维复指数信号 最小二乘估计 信号处理
