摘要： A TDMA communications apparatus is provided with a central processor and a control circuit for resetting or fine-adjusting a count value of a slot timing generating counter which generates slot timing pulses used for establishing synchronization of communication. The central processor switches the apparatus to coarse adjustment mode upon detecting RSSI level of a signal received from specific one of other stations. Then, the central processor switches the apparatus to verification mode to verify that data of individual slots are correctly received for a specific period of time and proceeds to fine adjustment mode, in which the central processor fine adjusts the count value of the slot timing generating counter so as to track the signal from the specific station using it as a tracking station.

摘要： If own station detects that a slot S2 previously reserved for own transmission has been occupied by another station when transmitting a message at a current slot S3, the own station sets the occupied slot to a time-out value of zero S0 upon transmitting the message at the current slot S3. At the same time, the own station re-reserves a new slot S5 within an SI in a succeeding frame so that transmission from the own station at the new slot S5 does not conflict with transmission from the other station at the occupied slot, now reserved by other station as slot A.
摘要翻译：如果本台在当前时隙S3发送消息时检测到先前为自己的传输预留的时隙S2已经被另一个站占用，则本站将发送消息的占用时隙设置为零S0的超时值当前时隙S3。同时，本站在后续帧内重新预留SI内的新时隙S5，使得新时隙S5处的本站的传输与被占用时隙中的其他站的传输不冲突，现在保留由其他站作为插槽A.

摘要： The present invention relates to a radio receiver or a diversity receiver where reception waves respectively reaching a plurality N of branches in parallel are cyclically selected at a first frequency equal to a value of the product of a symbol frequency, the plurality N being a total number of branches, and a prescribed number E equal to or greater than “2”, the instantaneous values of selected reception waves are sequentially sampled at a second frequency equal to or higher than the first frequency, and a resulting sequence of instantaneous values is cyclically split at the first frequency, whereby sequences of instantaneous values individually corresponding to the plurality N of reception waves are output. In a radio transmission system applying the above radio receiver or diversity receiver, reception waves reaching a plurality of branches are received in parallel without largely increasing hardware in scale.
