摘要： A communication system comprises a master station 21 and a plurality of slave stations 22-1 to 22-N each of which communicates with the master station through a radio channel carrying a communication signal by using time division multiple access. The slave stations are similar in structure to one another. The master station is similar in structure to each of slave stations. Each of the slave stations selectively transmits a speech signal and an image signal to the master station. On transmitting the speech signal, the speech signal is converted into an ADPCM signal. On transmitting the image signal, the image signal is converted into a PCM signal. The master station receives the communication signal which is transmitted from each of the slave stations. The master station detects whether or not the communication signal is representative of the ADPCM signal to selectively produce the speech signal and the image signal.
摘要翻译：通信系统包括主站21和多个从站22-1至22-N，每个从站22-1至22-N通过使用时分多址访问通过携带通信信号的无线电信道与主站进行通信。从站在结构上相似。主站的结构与每个从站类似。每个从站选择性地向主站发送语音信号和图像信号。在发送语音信号时，语音信号被转换成ADPCM信号。在发送图像信号时，图像信号被转换成PCM信号。主站接收从每个从站发送的通信信号。主站检测通信信号是否代表ADPCM信号，以选择性地产生语音信号和图像信号。

摘要： A communication terminal interface accepts, on different channels, information in a plurality of formats for communication purposes over a communication link which may be a TDMA satellite link. Each channel is accepted by a different interface unit which serves to format the information for communication over the system. This unit includes a compression-expansion buffer memory for allowing information received at a receive rate R.sub.s to be multiplexed and transmitted at a transmission rate T.sub.s which may be many times higher than the receive rate. In addition some units may include forward acting error correcting coding selected to provide the necessary corrected bit error rate for the type of information accepted by the unit and the capacity of the communication link over which the information is to be transmitted. The transmitter may employ differential encoding. To avoid increasing the error rate, which would normally result from this type of encoding, the encoded data is interleaved at the transmit side such that adjacent errors, after de-interleaving, on the receive side, are sufficiently displaced such that they may be corrected by the error decoding.
摘要翻译：通信终端接口通过可能是TDMA卫星链路的通信链路在不同信道上接收用于通信目的的多种格式的信息。每个通道被不同的接口单元接受，该接口单元用于格式化用于通过系统进行通信的信息。该单元包括用于允许以接收速率Rs接收的信息以可能比接收速率高多倍的传输速率Ts被复用和传输的压缩扩展缓冲存储器。此外，一些单元可以包括被选择为向该单元接受的信息类型提供必要的校正误码率的正向作用纠错编码以及该信息将被发送的通信链路的容量。发射机可以采用差分编码。为了避免增加通常由这种类型的编码造成的错误率，编码数据在发送侧进行交织，使得在解交织之后在接收侧的相邻错误被充分地移位，使得它们可以被校正通过错误解码。

摘要： The frame timing control of TDMA signals in cellular systems is implemented in mobile stations and/or base stations according to the invention so that the functions are divided between the frame timing control unit (1) and the microcontroller (2). In this way, the frame timing can be controlled in a flexible manner, for instance when moving from one TDMA cell type to another, without breaking the speech or data communication.

摘要： A method and system for controlling admission to a packet switched radio channel (PRCH) is provided. A PRCH admission control function (416) evaluates admission requests for users requesting admission to a PRCH. The admission requests each contains a priority value and an estimated data traffic for the requesting user. If the estimated data traffic from one or more packet calls currently using the PRCH and having a priority equal to or higher than the priority of the requesting user, plus the estimated data traffic required by the requesting packet call are less than a maximum tolerable traffic level, the packet call is granted admission (710).
