摘要： The present invention provides a method and apparatus for transmitting a preamble for multiple channel estimation. The method includes generating a channel estimation sequence, allocating the channel estimation sequence to some of a plurality of symbols in which a preamble is transmitted, and transmitting the preamble. The channel estimation sequence is generated by bisecting a sequence having a length N, generating a first sequence and a second sequence by adding a Zero-padded Suffix (ZS) having a zero value to a last part of each of the two bisected sequences, copying the first sequence and the second sequence at least once, and allocating the first sequences and the second sequences to some of the symbols.

摘要： In accordance with an elevator system for controlling a response to a call of the present invention, each of sub-controllers includes a unit of storing the information regarding service ability to a hall call, and a unit of determining service ability based on the information stored in the unit when the call is generated from the hall, regardless of a call response signal from a main controller. As a result, the determination and display of service ability to the hall call can be rapidly exactly performed. In addition, the main controller includes a unit of checking and determining abnormality of the sub-controllers, and a unit of storing an identifier of the abnormal sub-controller. Since the data is not transmitted to the abnormal sub-controller, a data transmission amount may be decreased. Also, during the repair or replacement work of the abnormal sub-controller, an identifier thereof can be rapidly confirmed. Moreover, the sub-controller includes a unit of checking and determining abnormality of the main controller. When the main controller is abnormally operated, a response lamp is turned off. As a result, the passengers are informed of that the elevator car is not able to provide the service, and thus do not unnecessarily wait for the elevator car at the hall.

摘要翻译： 根据用于控制对本发明的呼叫的响应的电梯系统，每个子控制器包括存储关于门厅呼叫的服务能力的信息的单元，以及基于存储的信息确定服务能力的单元 在从主厅产生呼叫的单元中，不管来自主控制器的呼叫响应信号如何。 结果，可以快速准确地执行对门厅呼叫的服务能力的确定和显示。 此外，主控制器包括检查和确定子控制器的异常的单元以及存储异常子控制器的标识符的单元。 由于数据不发送到异常子控制器，所以可以减少数据传输量。 此外，在异常子控制器的维修或更换工作期间，可以快速确认其识别符。 此外，副控制器包括检查和确定主控制器的异常的单元。 当主控制器异常操作时，响应灯熄灭。 结果，通知乘客电梯轿厢不能提供服务，因此不必不必要地等待电梯轿厢在大厅。
