One of the world-wide cooperative computing tasks is the "Grand Internet Mersenne Prime Search" -- GIMPS -- striving to find ever-larger prime numbers by examining a particular category of such numbers. A Mersenne number is defined as a number of the form (2p–1), where p is a prime number -- a number divisible only by one and itself. (A number that can be divided by numbers other than itself and one are called "composite" numbers, and each of these can be uniquely represented by the prime numbers that can be multiplied together to generate the composite number — referred to as its prime factors.) Initially it looks as though the Mersenne numbers are all primes. Prime Corresponding Mersenne Number 2 4–1 = 3 -- prime 3 8–1 = 7

资源描述本文基于面阵提出一种UNITARY-ESPRIT算法解决非相干信源的二维DOA估计问题，利用酉变换把复值导向矩阵和复协方差矩阵转换为实值计算，因此特征值分解或者奇异值分解仅在实数域下进行，大大降低运算复杂度，而且估计性能优于传统的ESPRIT算法。
