Title:
WIRELESS COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2014/097420
Kind Code:
A1
Abstract:
The objective of the invention is to record, in a wireless communication apparatus, received data before a reception process and demodulated data after the reception process in such a manner that the received data before the reception process and the demodulated data after the reception process are associated with reception timings of the received data, thereby analyzing, with high precision, the reception conditions of wireless signals at the reception timing level. A signal recording unit (405), while recording, into memory (406), received data (408) from ADC unit (403) at each of a plurality of recording timings, receives, from a reception process unit (404) that demodulates the received data (408), a symbol number (409), which is assigned to the demodulated data that is demodulated by the reception process unit (404), and a demodulated symbol (410) in synchronization with the recording timing. The signal recording unit (405) creates a table (407) for storing the symbol number (409) and demodulated symbol (410) in such a manner that the symbol number (409) and demodulated symbol (410) are associated with the recording timing, and further, the signal recording unit (405) records the received data (408) before the reception process and the demodulated data after the reception process by the reception process unit (404) in such a manner that the received data before the reception process and the demodulated data after the reception process are associated with the reception timing of the received data.
