IPC: G06F7/548
Filed: 1988-02-17
Abstract: PURPOSE:To decrease the hardware quantity by using a barrel shifter, the 1st and 2nd addition/subtraction units, and a stack which controls the arithmetic operations carried out by both addition/subtraction units. CONSTITUTION:The registers 111 and 121 store two types of variables and the addition/subtraction units 112 and 122 perform the prescribed addition or subtraction. A barrel shifter 113 shifts the contents of the register 121 to the right by an optional even number of digits. A barrel shift 114 multiplies the output of the unit 112 by 1/2 and a shifter 124 doubles the outputs of the unit 122. Then an exponent part computing element 103 controls the shift value of the shifter 113 and the address of a ROM 104 and performs the arithmetic operations of an exponent part. A stack 105 decides the addition or the subtraction that is carried out by both units 112 and 122.

Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To estimate the three-dimensional directivity of the basic station antenna in mobile communication, for example, accurately under operating state even in an urban environment where buildings are arranged intricately. SOLUTION: An observation point is located at a position where a primary wave source, i.e., an antenna to be measured, can be observed. The direct wave from the primary wave source and the reflected wave are then received and the three-dimensional coordinates and the intensity are determined for the primary wave source and a mirror image wave source corresponding to the reflected wave by two frequency hologram observation (Step 101). Subsequently, the azimuth and the incident angle of reflection point corresponding to the mirror image wave source viewed from the primary wave source are determined for each mirror image wave source (Step 102). Finally, a reflection coefficient is determined from the incident angle at that reflection point, and the like, for each reflection point and the intensity of mirror image wave source is multiplied by the reciprocal of the reflection coefficient thus determining the antenna directivity in the direction of that reflection point for the primary wave source.
