Latest Patents

One of Gazelle's latest patents is titled "Equalizer performance enhancements for broadband wireless applications." This patent describes a system and method for enhancing the performance of an equalizer in a modem. Several techniques are disclosed that improve modem performance. The first technique utilizes stored parameters for each burst from remote sites to demodulate a received data stream. The second technique compensates for gain droop caused by storing parameters across each burst. The third technique minimizes errors by analyzing the signal-to-noise ratio and error rate of the received burst. The fourth technique enhances equalizer convergence using a two-part preamble with different modulation techniques. The fifth technique allows for a soft reset of the modem without a complete reset. The sixth technique determines a modem adaptation factor based on the expected modulation type of incoming burst transmissions. Lastly, the seventh technique calculates a phase correction value for stored tap values and applies it to the incoming signal.

Another notable patent is the "System and method of automatically calibrating the gain for a distributed wireless communication system." This invention provides a wireless broadband connection between base stations and customer sites. The system includes indoor units that communicate across cables to outdoor units, which transmit and receive wireless data. The indoor units control the outdoor units by sending digital messages along the interface cables. This system allows for automatic calibration of the receive path gain in base stations, compensating for cable discrepancies. An improved transmit power control technique that is unaffected by modulation type is also described.
