摘要： This invention extends Alamouti's scheme for wideband TDMA systems; it then works in conjunction with time-domain equalization. In fact, the present invention envisages time-domain DFE or MLSE equalization (which is more robust than linear frequency-domain equalization) via the use of a training mid-amble to separate adjacent sub-blocks; this mid-amble is used in equalizer training and its direct and inter-symbol interference contributions to the received signal, are subtractively eliminated to facilitate the detection process itself. This approach may be applied to all systems in time-dispersive propagation media, where the burst or slot length is short enough that the fading can be considered time-invariant over its duration.

摘要： A method for controlling an adaptive antenna array (50) is provided and includes receiving a plurality of signals, each signal including a series of signal data symbols (42) and signal non-data symbols (38, 40) divided into symbol transmission units with the signal non-data symbols (38, 40) disposed among the signal data symbols (42) in each unit and each signal related to the other signals of the plurality of signals as reflections of an original signal. The method also includes separating the signal non-data symbols (38, 40) from the signal data symbols (42), and comparing the signal non-data symbols (38, 40) to a set of known non-data symbols. The method further includes determining a set of weights according to the comparison of the signal non-data symbols (38, 40) to the set of known non-data symbols, the weights to be combined with the signal data values (42) to limit the effect of interference on the signal data symbols (42). An adaptive antenna array (50) is also provided including a weight calculator (62) including a program which controls the weight calculator (62) to perform the comparing (88, 90) and determining steps (94) of the method discussed above.

摘要： A method determines the signal usability of an adjacent channel in a multi-cell communication system without the aid of synchronization symbols. In general, a three step search is used to arrive at the adjacent channel signal quality. The first step is a coarse timing phase search. This is accomplished through a signal quality estimates (606). The second step arrives at the optimum time phase by first interpolating (608) the received signal around the time phase selected in the first step to generate additional samples. After the interpolation (608), signal quality estimates are calculated (610) for the time phases immediately surrounding the time phase found in the first step. The optimum time phase corresponds to the maximum of these quality estimates. Finally, in the third step, the signal quality estimate is calculated for the optimum time phase. This provides the adjacent channel signal quality estimate desired.

摘要： Systems, methods and apparatus are provided for scheduling resources in Orthogonal Frequency-Division Multiple Access (OFDMA) communication networks for “direct link” or peer-to-peer communications among stations operating therein so that OFDMA resources can be allocated to a transmitter station for a peer-to-peer communication session with a receiver station such that near-far issues caused by peer-to-peer communication are reduced/avoided. The disclosed technologies can prevent peer-to-peer communication links using different sub-channels within the same time slot from creating near-far issues for other receiver stations that are within communication range.

The measured performance information includes at least one quality metric associated with a downlink signal sent from the evolved Node B to the one or more stations. The evolved Node B determines excluded timeslots and preferred timeslots based on current resource assignments in each timeslot and based on the peer sets, marks potential resources in an uplink portion of a resource allocation map, and allocates one of the potential resources for peer-to-peer communication between a transmitter station and one or more receiver stations.

摘要： A method and apparatus for synchronizing a node (200) within an ad-hoc communication system (100) is described herein. During operation all nodes periodically broadcast a synchronization beacon for other nodes to utilize for synchronization when a coordinating access point (node) is unavailable. A particular node's synchronization beacon will have an associated “tier” number that is incremented from the tier number of the beacon used to synchronize the particular node. In the absence of an access point, a node that joins the ad-hoc communication system will listen for synchronization beacons transmitted by other nodes. If synchronization beacons are heard, the node will synchronize with a beacon having a lowest tier. The node will then broadcast its own beacon having its tier number incremented from the lowest tier beacon heard.

摘要： A base station allocates resources for peer-to-peer communications by creating or updating peer sets from measured performance information received from one or more stations. Based on current resource assignments in each timeslot and based on the peer sets, the base station determines excluded timeslots and preferred timeslots. The base station then marks potential resources in a portion of a resource allocation map. One of the potential resources is allocated for peer-to-peer communication between a transmitter station and one or more receiver stations.

摘要： A method of selecting one or more active slave wireless devices from a plurality of active/parked slave wireless devices is implemented by a master wireless device. The master wireless device initially assigns sequential weights to each active/parked slave wireless device, and subsequently designates one or more of the active/parked slave wireless devices as active slave wireless device(s) based partially or entirely on the assigned sequential weights. The assignment of sequential weights can be accomplished by assigning each active/parked slave wireless device to one of a plurality of ranked groups collectively representative of various traffic types between a base site and the active/parked slave wireless devices. Each active/parked slave wireless device is then sorted within its respective group.
