A communication apparatus, method, and system are provided. The communication apparatus receives through a transmission path a combined signal in which modulated signals are combined. The communication apparatus converts a channel matrix indicating transmission characteristics of the transmission path using a basis conversion matrix which converts column vectors forming the channel matrix to cross at right angles, estimates a transmission symbol using the converted channel matrix, and calculates a likelihood of each bit of the estimated transmission symbol being a “1” and a “0”, respectively, using an inverse matrix of the basis conversion matrix. The method includes converting a channel matrix; estimating a transmission symbol; and calculating a likelihood of each bit being a “1” and a “0”, respectively, of the estimated transmission symbol using a basis conversion matrix. The system includes a transmitter and receiver for transmitting and receiving, respectively, a combined signal according to the method.

A receiving apparatus includes a combining and quantizing unit that combines channel vectors corresponding to a combination of a plurality of antennas in order to generate a combination channel vector and selects a predetermined quantization vector according to the generated combination channel vector, an error detecting unit that detects whether there is an error in received signals, and an antenna switchover unit that switches over the combination of the antennas according to a result of the error detection, in which the combining and quantizing unit feeds an index of the selected predetermined quantization vector back to a transmitting apparatus. In this way, diversity effect can be obtained by means of repeat control while reducing the amount of feedback information.

Provided are a rolled Mg alloy material which has a wide width and whose mechanical properties are uniform in a width direction, a Mg alloy structural member produced by plastically working the rolled Mg alloy material, and a method for producing the rolled Mg alloy material. The method for producing a rolled Mg alloy material includes rolling a Mg alloy material with a reduction roll. The Mg alloy material has a width of 1,000 mm or more, and the reduction roll has three or more regions in the width direction. The temperature is controlled in each of the regions so that a difference between a maximum temperature and a minimum temperature is 10° C. or less in the width direction of a surface of the reduction roll. The variation in the rolled state in the width direction can be reduced by reducing a difference in temperature over the width direction of the reduction roll. As a result, it is possible to produce a rolled Mg alloy material whose mechanical properties are substantially uniform in the width direction.

A switch assembly (1) comprises a push-button section (52) and a push-button body (53) as an operation transmitting member, an LED box (54) and a contact-making contact (56) as a direct functioning member, and a communication-function incorporating contact (communications contact) (55) as an information input/output functioning member, as permitting these components to be connected with each other. Therefore, the switch assembly can respond to an operation given to the push-button body (52) by causing the contact-making contact (56) to provide an output for switching between a conductive state and a non-conductive state and by causing the communications contact (55) to output an information signal to a network.
