Some new results of regular Hadamard matrices and SBIBD II
In this paper we prove that there exist 4—{k2; 1/2k(k—1); k(k—2)} SDS, regular Hadamard matrices of order 4k2, and SBIBD(4k2, 2k2 + k, k2 + k) for k = 47, 71, 151, 167, 199, 263, 359, 439, 599, 631, 727, 919, 5q1, 5q2N, 7q3, where ql, q2 and q3 are prime power such that ql ≡ 1(mod 4), q2 ≡ 5(mod 8) and q3 ≡ 3(mod 8), N = 2a3bt2, a, b = 0 or 1, t ≠ 0 is an arbitrary integer. We find new SBIBD(4k...
متن کاملA Series of Regular Hadamard Matrices
Let p and 2p − 1 be prime powers and p ≡ 3 (mod 4). Then there exists a symmetric design with parameters (4p, 2p − p, p − p). Thus there exists a regular Hadamard matrix of order 4p. AMS classification numbers: 05B20, 05B05
متن کاملSome Infinite Classes of Hadamard Matrices
A recursive method of A. C. Mukhopadhay is used to obtain several new infinite classes of Hadamard matrices. Unfortunately none of these constructions give previously unknown Hadamard matrices of order <40,000.

متن کاملOn some applications of Hadamard matrices
Modern communications systems are heavily reliant on statistical techniques to recover information in the presence of noise and interference. One of the mathematical structures used to achieve this goal is Hadamard matrices. They are used in many different ways and some examples are given. This paper concentrates on code division multiple access systems where Hadamard matrices are used for user...
