摘要： According to the invention, an information signal, such as a information signal, is sampled, quantized and processed digitally through an information encoder. Digitally processed samples produced by the encoder are modulated onto a communication channel to create channel symbols having a magnitude of modulation proportional to a characteristic of a respective digitally processed sample. Both a radio frequency (RF) transmission embodiment, and a wireline embodiment are provided. In a final aspect of the present invention, encryption is provided to ensure communication privacy.

摘要： An RF communications system that can determine when a requesting subscriber unit comprises a TDM capable unit, and when it doesn't. Channel assignments are based upon this determination. The system also includes repeaters that can translate communications in a TDM format as transmitted by a TDM capable unit into non-TDM format for subsequent transmission to a non-TDM capable unit, and vice versa.
摘要翻译： RF通信系统，其可以确定请求用户单元何时包括具有TDM能力的单元，以及何时不能。频道分配基于此决定。该系统还包括中继器，其可以将由TDM能力单元发送的TDM格式的通信转换为非TDM格式，用于随后传输到不支持TDM功能的单元，反之亦然。

摘要： In a digital communication system, a residual signal is generated, encoded, and combined with an encoded information signal in a manner that does not appreciably degrade the encoded information signal. The information contained within the residual signal may be used by the receivers to improve the quality of the recovered signal. The residual signal is modulated such that it may only be recovered when the signal-to-noise ratio is sufficiently high. In this way, the quality of the recovered signal improves with increased signal-to-noise ratio.

摘要： A TDM cellular communication (100) system includes a plurality of repeaters (102) each providing communication coverage for a cell site. A plurality of communication units communicate with the repeaters. The communication units are handed off from one cell site to another by measuring the range of the communication units from the repeaters. If the range exceeds a predetermined range the received signal quality of the adjacent cell site repeaters are measured. An available cell site which provides the best received signal quality is selected by the communication unit for hand off.

摘要： Uplink time slots (108) may be allocated within a communication system (100) when a communication unit (102) transmits a first packet (501) to a time slot allocator (101). Upon receiving the first packet (501), the time slot allocator (101) determines whether the first packet (501) contains a request for allocation of N uplink time slots. When the first packet (501) contains the request for allocation of N uplink time slots, the time slot allocator (101) allocates the N uplink time slots to the communication unit (102) when the N uplink time slots are available, wherein the N uplink time slots are allocated contiguous in time. The time slot allocator (101) then transmits an allocation indication to the communication unit in each of N downlink time slots (110) corresponding to the N allocated uplink time slots (108) to inform the communication unit (102) of the allocation.
摘要翻译：当通信单元（102）将第一分组（501）发送到时隙分配器（101）时，上行链路时隙（108）可以被分配在通信系统（100）内。在接收到第一分组（501）时，时隙分配器（101）确定第一分组（501）是否包含分配N个上行链路时隙的请求。当第一分组（501）包含分配N个上行链路时隙的请求时，当N个上行链路时隙可用时，时隙分配器（101）向通信单元（102）分配N个上行链路时隙，其中N 上行链路时隙在时间上被分配连续。时隙分配器（101）然后在对应于N个分配的上行链路时隙（108）的N个下行链路时隙（110）中的每一个中向通信单元发送分配指示，以通知通信单元（102）的分配。

摘要： In a Radio Frequency (RF) communication system using Time Division Multiple Access (TDMA) having time slots of a common duration, a quantity of information bits to be transmitted is provided. Based at least in part on the number of information bits to be transmitted, a modulation technique is selected from a plurality of modulation techniques. Based at least in part on the modulation technique selected and the common duration of the time slots, the information bits are formatted into blocks, each block containing an equal number of information bits. The blocks are transmitted in the time slots such that a predetermined symbol rate is maintained.

摘要： A radio communication system controller embodies the present invention by providing extended use (306) of a communication resource (106) to a plurality of communication units. The inventive method includes the steps of assigning (402) a first communication resource to a first communication unit, and then temporarily configuring (406) the assigned communication resource as a reserved resource. The controller then receives (408), from a second communication unit, a request to transmit a second communication on the assigned communication resource. Lastly, the controller re-configures (412) the assigned communication resource to allow transmission of the second communication on the assigned communication resource.

摘要： A method of providing a communication unit (10) access to a shared communication resource. In the communication unit, a clock (123) is maintained, and the unit detects the time when an inhibit period on the shared communication resource begins, and the time at which it concludes. When access to the shared communication resource is desired, the unit attempts to access the communication resource based on the time at which access was desired, as well as the times at which a detected inhibit condition began and concluded. A virtual time clock runs only during non-inhibit periods. Access to the communication resource is then based on when the virtual time clock equals the desired access time.
摘要翻译：一种提供通信单元（10）访问共享通信资源的方法。在通信单元中，保持时钟（123），并且单元检测到共享通信资源的禁止期间开始的时间和其结束的时间。当期望访问共享通信资源时，单元基于期望接入的时间以及检测到的禁止条件开始和结束的时间来尝试访问通信资源。虚拟时钟仅在非禁止期间运行。然后，基于虚拟时钟等于所需访问时间的时间，访问通信资源。
