    Abstract: Various embodiments are described to address the need for providing wireless backhaul that may reduce operator startup costs while avoiding some of the drawbacks present in the prior art approaches. Generally expressed, the wireless network equipment (WNE) (121) of a collector cell provides access to a backhaul network (151) to one or more neighboring cells (122) via in-band wireless signaling. Given the frequency bands used by the collector cell WNE for communication with remote units, one portion of each band used for user traffic while another portion of each band is used for backhaul traffic. Having backhaul and user traffic share the assigned frequency bands can eliminate the need to license additional bands for wireless backhaul. Moreover, utilizing a portion of the existing, in-band orthogonal channels may be more spectrally efficient than using a separate radio in the same band.

    Abstract: A code division multiple access (CDMA) communication system (100) has improved control by accurately characterizing coverage and loading parameters related to the CDMA communication system (100). To accurately characterize coverage and loading parameters related to the CDMA communication system, parameter meshes corresponding to parameters of the CDMA communication system are generated. The parameter meshes are evaluated, either individually or in combination, to provide comprehensive information regarding the performance of the CDMA communication system. Based on the results of the evaluation, a controller (113) within the CDMA communication system (100) controls the parameters to improve call quality, loading, etc. of the CDMA communication system (100).

    Abstract: A data message transmission system for a cellular radiotelephone system provides protection against data loss caused by multipath fade and subscriber unit handoff. Data from data terminal equipment (801) to be transmitted is converted by a system data processor (805) and radio signalling interface (807) into a format compatible with radio transmission prior to transmission by a transceiver (809). The data is reconverted to its original format following reception. Handoff is accomplished by halting the data transmission prior to handoff and resuming data transmission after handoff. Call supervision occurs via busy-idle bit coding performed in radio signalling interface (807).

    Abstract: A method and apparatus for diversity reception in a communication system is provided. A dual branch receiver (100, 101) is provided with a stored replica of expected reference information (104) so that correlation with received time-dispersed signals produces an estimate of the transmission channel's impulse response as seen by each branch (100, 101), and determines, among other things, phase error between the branch local oscillators (208, 209) and the time-dispersed signals. Matched filters (214, 215) are constructed which then coherently align the time-dispersed signals from each branch (100, 101) with that branch's local oscillator (208, 209) which constitutes a part of the signal equalization. A diversity processor (105) performs bit by bit selection on the re-aligned signals, maximal ratio combining of the re-aligned signals, or equal gain combining of the re-aligned signals, followed by a sequence estimation which uses similarly selected or combined channel distortion compensation parameters to complete the equalization process on the new signal.

    Abstract: A communication system dynamically assigns channels to a subscriber unit so as to, inter alia, mitigate the effects of co-channel interference in the system. The communication system has a plurality of base-stations receiving the transmission of a subscriber unit desiring service. Upon receipt of the subscriber unit's transmission, each base-station determines a signal quality value, which it then reports to a system controller. The system controller determines the best signal quality value reported and assigns a channel to the base-station which reported the best signal quality value. The chosen base-station transmits to the subscriber unit on an assigned channel to establish communication. The assigned channel transmitted by the chosen base-station need not be associated with the channel the subscriber transmits on. In fact, either channel may be any one of the channels allocated for use by the communication system.

    Abstract: A communication system dynamically assigns channels to a subscriber unit so as to, inter alia, mitigate the effects of co-channel interference in the system. The communication system has a plurality of base-stations (111, 112, 115, 118) receiving the transmission of a subscriber unit (120, 100, 121) desiring service. Upon receipt of the subscriber unit's transmission, each base-station determines a signal quality value, which it then reports to a system controller (210). The system controller determines the best signal quality value reported and assigns a channel to the base-station which reported the best signal quality value. The chosen base-station transmits to the subscriber unit on an assigned channel to establish communication. The assigned channel transmitted by the chosen base-station need not be associated with the channel the subscriber transmits on. In fact, either channel may be any one of the channels allocated for use by the communication system.

    Abstract: An equalization system for equalizing a corrupted signal is disclosed. The equalization system includes a complex matched filter (400) and a maximum likelihood sequence estimator (MLSE) (405) for removing the effects of phase shift, amplitude variations, intersymbol interference, etc. resulting from multi-pathing and noise contributed by the receiver front end. The system estimates a correlation signal C(t) (505) and synchronizes C(t) 505 to maximize its energy as seen on the taps of the complex matched filter (400). Taps having amplitude coefficients below a predetermined threshold are set to zero to produce a modified CIR estimate. The modified CIR estimate which has had the effects of noise virtually eliminated, is then used to construct the complex matched filter (400) and is also used as input to the MLSE (405) to produce a better equalized data signal.
