摘要： A method and apparatus in a communications system (100) for providing communications units (134) access to the communications system (100). The communications. system (100) includes a cable distribution network (106) with an base communications unit (102) and a number of downstream communications units (134) all connected to the cable distribution network (106). A plurality of channels are used to transmit data between the base communications unit (102) and the downstream communications units (134). A first set of channels are used primarily for access the communications system (100) and a second set of channels are used for transmitting data within the communications system (100) after access to the communications system (100) has been gained. The base communications unit (102) sends a first type of data transmission including an identification of access channels used for requesting access to the communications system (100). The base communications unit (102) assigns channels within the second set of channels response to receiving a request for access to the communications system (100) on the first set of channels. A mechanism also is provided for handling collisions in transmissions between the downstream communications units (134) to the base communications unit (102) in attempting to gain access to the communications system (100).

摘要： The process of the present invention generates an optimum automatic frequency control signal in an apparatus that has a plurality of adaptive algorithms, each adaptive algorithm having a reference signal with an associated frequency dither. The process starts by comparing the performance of each of the plurality of adaptive algorithms. This difference is input to a comparator where it is compared to zero. This delta signal then modifies the numerically controlled oscillator frequency. After several iterations, the frequency offset is reduced to substantially zero.

摘要： A method of retaining channel use by a secondary system is described. A secondary channel used during periods of normal communication between a secondary transmitter and receiver is split into sub-bands for use during a quiet period containing quiet phases. During the quiet period, while the transmitter communicates with the receiver on one sub-band, the receiver simultaneously senses for incumbent devices on another sub-band, as well as vice-versa. Transmission and sensing do not occur simultaneously on the same sub-band and transmission is limited to only one of the sub-bands. Transmission and sensing are performed by both the transmitter and the receiver on every sub-band over the course of the quiet period. The locations of secondary receivers are determined and employed during scheduling such that devices sufficiently separated from each other transmit during different quiet phases and transmit and sense in sub-bands separated by another sub-band.
摘要翻译：描述了通过辅助系统保持信道使用的方法。在次级发射机和接收机之间的正常通信期间使用的辅助信道被分成子带，以在包含安静阶段的安静时段期间使用。在静音期间，当发射机与一个子频带上的接收机进行通信时，接收机同时检测另一个子频带上的现有设备，反之亦然。传输和感测不会在同一子带上同时发生，传输仅限于一个子带。在安静时段的过程中，发射机和接收机都在每个子频带上执行传输和传感。在调度期间确定并采用辅助接收机的位置，使得彼此充分分离的设备在不同的安静阶段期间发送，并在由另一个子频带分离的子频带中进行发送和检测。

摘要： A baseband detector includes a complex differential detector, a constellation point computer, and a phase shift keying (PSK) decoder. The complex differential detector outputs complex values in response to digitized samples derived from a received baseband signal. The PSK decoder generates decoded bits representing information symbols by determining in minimum distance between the complex values and plural constellation points provided by the constellation point computer. The constellation point computer can adaptively generate the constellation points based on a training sequence of information symbols and their corresponding complex valued outputs from the complex differential detector. The baseband detector can be used for frequency shifting keying (FSK) and differential phase shift keying (DPSK) demodulation in direct conversion receivers (DCRs).
