发明名称 METHOD AND APPARATUS FOR GENERATING COUPLING HADAMARD CODE, AND COMMUNICATION METHOD AND SYSTEM EMPLOYING SAME
摘要 <P>PROBLEM TO BE SOLVED: To provide a coupling Hadamard code generating method and apparatus, and communication method and system employing the same. <P>SOLUTION: A coupling Hadamard code generating method includes the steps of: generating an (N&times;N)-dimensional Hadamard matrix A and an (N<SP>2</SP>&times;N<SP>2</SP>)-dimensional Hadamard matrix B; forming an (N<SP>2</SP>&times;1)-dimensional column vector (a) by overlapping into one all columns of the generated Hadamard matrix A; and performing Hadamard multiplication multiplying elements of the Hadamard matrix B by elements of corresponding rows of the column vector (a) to generate an (N<SP>2</SP>&times;N<SP>2</SP>)-dimensional fundamental coupling Hadamard matrix (N is an integer multiple of the number of transmitter antennas and is &ge;2) wherein each column is a fundamental coupling Hadamard code. <P>COPYRIGHT: (C)2007,JPO&INPIT
