Fixed radio equipment serving as a base station includes a transmitter, a plurality of antennas, and a selective control circuit. The antennas are spaced apart from each other by a distance which minimizes a correlation of interferential fading. The transmitter modulates a carrier by identical signals to be transmitted during periods associated in number with the antennas and feeds the resulting bursts of the carrier time-serially to a selective control circuit. The selective control circuit delivers one of the successive bursts of the carrier fed from the transmitter to one of the antennas and then delivers another burst following the above-mentioned burst to another one of the antennas. Mobile radio equipment or station has a single antenna for receiving the identical signals transmitted time-serially from the base station. The mobile station selects and outputs either one of the received signals which has higher quality than the other.

A recording/reproducing apparatus includes an encoding section, a decoding section, and a first judging section. The encoding section is configured to encode data that is to be recorded onto a recording medium into an LDPC (Low Density Parity Check) code. The decoding section is configured to decode the LDPC code read out from the recording medium. The judging section is configured to judge a block with a recording error based on one of a block error flag and an iterative decoding count output from the decoding section.

Scanning rate in a capacitance change measuring circuit for a capacitive sensor device is enhanced. The circuit includes: an electrode drive section line-sequentially applying an input pulse signal to a plurality of columns of first electrode patterns in the capacitive sensor device; a peak hold circuit storing a peak level of a detection signal extracted from each column of second electrode patterns into a capacitive element as a corresponding potential; a current source initializing the potential in the capacitive element within one period of the input pulse signal; a comparator comparing the potential in the capacitive element with a reference value; and determination sections each determining whether or not an input operation using a human body or the like is executed, based on a timing information and a reference timing information, the timing information representing a timing when the potential held in the capacitive element crosses the reference value.
