Abstract
Official abstract text for this publication.
A satellite radiowave receiving device includes: a receiving unit which receives a radiowave signal; a conversion unit which converts the radiowave signal into digital data; a detection/arithmetic operation unit which detects the satellite signal; a capturing unit which searches a reception frequency; a setting unit which sets a second bit number, and the number of parallel processing in which the predetermined arithmetic operation can be executed in parallel; and a specifying unit which specifies the reception frequency of the satellite signal, and the detection/arithmetic operation unit executes the predetermined arithmetic operation in parallel for the input signal data related to reception frequencies of which number is equal to or less than a predetermined number of maximum parallel processing, and the number of parallel processing is determined so that a total bit number is equal to or less than the maximum bit number/the number of maximum processing.
First claim
Opening claim text (preview).
What is claimed is: 1. A satellite radiowave receiving device comprising: a receiving unit which receives a radiowave signal of a frequency band including a transmission frequency of a satellite signal transmitted on a radiowave from a positioning satellite; a conversion unit which converts the radiowave signal received by the receiving unit into digital data; a detection/arithmetic operation unit which performs a predetermined arithmetic operation to detect the satellite sign…
