Problems solved by technology

[0021] Since the conventional wireless base station apparatus is constituted as above, TRX15 is used for the error determination of the output signal (downlink signal) of BB16, and the error determination of the output signal (uplink signal) of TRX15 is performed by TRX15. BB16 is conducted, but there is a problem that the judgment results of both parties cannot be aggregated to make the final judgment, etc.

Embodiment Construction

[0041] Hereinafter, in order to describe the present invention in more detail, the best mode for carrying out the present invention will be described with reference to the drawings.

[0042] Embodiment 1

[0043] Fig. 2 is a structural diagram of a wireless base station device according to Embodiment 1 of the present invention. In the figure, 21 is a network that is connected to a plurality of wireless base station devices 22 through a wired transmission path to control a plurality of wireless base station devices 22. The control device (wired network), 22 is a wireless base station device that sends the transmission data output by the network control device 21 to the wireless terminal 23, and outputs the reception data sent by the wireless terminal 23 to the network control device 21, and 23 is a wireless terminal .

[0044]31 and 32 are a pair of antennas implementing transmit diversity and diversity reception, 33 is an outdoor receiving amplifier that amplifies the wireles...

Abstract

At the time of modulating transmission data, a radio transmitting and receiving part TRX (35) error-checks the transmission data and outputs the result of the error check, whereas a base band signal processing part BB (36) error-checks received data output from TRX (35) and makes a health check based on the result of the error check of the received data and the result of error check output from TRX (35).

Description

technical field [0001] The present invention relates to a CDMA (Code Division Multiple Access, Code Division Multiple Access) wireless base station device that performs signal normality checks between a baseband signal processing unit and a wireless transceiver unit. Background technique [0002] FIG. 1 is a configuration diagram of a conventional wireless base station device. In the figure, 1 is a network control device that is connected to a plurality of wireless base station devices 2 through a wired transmission path to control a plurality of wireless base station devices 2. The wireless base station device that transmits the transmission data output by the network control device 1 to the wireless terminal 3 and outputs the reception data transmitted by the wireless terminal 3 to the network control device 1, 3 is a wireless terminal. [0003] 11 and 12 are a pair of antennas that implement transmit diversity and diversity reception, and 13 is an outdoor receiving amplif...
