| 20080298339 | METHOD FOR FREQUENCY DIVISION DUPLEX COMMUNICATIONS - The high quality PCS communications are enabled in environments where adjacent PCS service bands operate with out-of-band harmonics that would otherwise interfere with the system's operation. The highly bandwidth-efficient communications method combines a form of time division duplex (TDD), frequency division duplex (FDD), time division multiple access (TDMA), orthogonal frequency division multiplexing (OFDM), spatial diversity, and polarization diversity in various unique combinations. The method provides excellent fade resistance. The method enables changing a user's available bandwidth on demand by assigning additional TDMA slots during the user's session. | 12-04-2008 |
| 20090245403 | METHODS AND APPARATUS FOR USE IN REDUCING RESIDUAL PHASE ERROR IN OFDM COMMUNICATION SIGNALS - Methods and apparatus for use in reducing residual phase error (RPE) in orthogonal frequency division multiplexed (OFDM) communication signals are described. In at least one embodiment of the invention, an apparatus includes a residual phase error estimator configured to estimate a residual phase error at least partially based on a plurality of phases of a first channel-compensated received signal and a plurality of phases of a sliced version of the first channel-compensated received signal. The residual phase error estimator is configured to correct a channel estimate at least partially based on the residual phase error estimate to thereby generate a corrected channel estimate. The apparatus includes a channel compensator configured to generate a second channel-compensated received signal at least partially based on a received signal and the corrected channel estimate. | 10-01-2009 |

| 20080298450 | Frequency Band Adaptive Wireless Communication - A system, apparatus and method is disclosed for multiband wireless communication. Frequency bands and/or transmission formats are identified as available within a range for wireless communication. Signal quality metrics for each frequency band are evaluated by a receiver to identify qualified frequency bands. The qualified frequency bands can be ranked according to one or more signal quality metrics, where the list of qualified bands can be communicated to a transmitter. The transmitter is arranged to evaluate the list of qualified bands and select a communication method based on the available frequency bands and a selected communication optimization scenario. Multiple frequency bands and communication methods can be utilized by the transmitter such that a combination of licensed, unlicensed, semilicensed, and overlapped frequency bands can be simultaneously used for communication. The receiver continually monitors communications and can report link performance to the transmitter for adaptive control of the selected communication methods. | 12-04-2008 |
