Abstract: Methods and apparatus are described for mitigating intercell interference in wireless communication systems utilizing substantially the same operating frequency band across multiple neighboring coverage areas. The operating frequency band may be shared across multiple neighboring or otherwise adjacent cells, such as in a frequency reuse one configuration. The wireless communication system can synchronize one or more resource allocation regions or zones across the multiple base stations, and can coordinate a permutation type within each resource allocation zone. The base stations can coordinate a pilot configuration in each of a plurality of coordinated resource allocation regions. Subscriber stations can be assigned resources in a coordinated resource allocation region based on interference levels. A subscriber station can determine a channel estimate for each of multiple base stations in the coordinated resource allocation region to mitigate interference.

Abstract: An output of a transmitter is looped back to an input of a receiver during a first time period while applying a frequency offset between the transmitter and the receiver. A first imbalance between an in-phase (I) branch and a quadrature-phase (Q) branch in the receiver is determined based on a signal received at the receiver during the first time period. The receiver is calibrated based on the determined first imbalance. After calibrating the receiver, the output of the transmitter is looped back to the input of the receiver during a second time period during which the frequency offset is not applied. A second imbalance between an I branch in and a Q branch in the transmitter is determined based on a signal received at the receiver during the second time period while the frequency offset is not applied. The transmitter is calibrated based on the determined second imbalance.

Abstract: This invention discloses an optimum form maximum likelihood MIMO detector (SFS ML Detector) that computes the LLR of the most likely received bit sequence from the received signal y, which consist of multiple signal stream from a MIMO channel H and an estimate of H. Through 5 simple steps of QR factorization, computation of partial Euclidean distance, sorting of the partial Euclidean distance, selection of surviving hypothesis by a set of algorithmic rule and computation of the full Euclidean distance of the survivors, and computation of the maximum likelihood from the surviving full Euclidean distance, the LLR of the received bit sequence can be obtained with a significantly lower number of computation and comparison than that is implied in the theoretical form of the maximum likelihood (ML) detector. There is no loss in performance of the SFS ML detector from the theoretical ML detector.

Abstract: In an orthogonal frequency division multiplex (OFDM) communication network, a node transmits an echo profile probe to other nodes in the network. The echo profile probe is a message that allows characterization of the unique echo profile through the communication channel between each node pair. The echo profile is used to calculate the cyclic prefix length needed for optimum communication from one node to the other.
