Patent number: 9088388Abstract: 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.Type: GrantFiled: April 7, 2014Date of Patent: July 21, 2015Assignee: AT&T Mobility II LLCInventors: Siavash Alamouti, Eduardo F.

Patent number: 8594138Abstract: Improvements are disclosed for in-band signaling, i.e., transmission of data in a voice channel of a digital wireless network during a voice call session. A family of narrow-band signaling methods, some employing tapered waveforms, is disclosed to successfully pass data-carrying signals through the low-bit rate modes of the EVRC-B vocoder commonly used in CDMA wireless channels. These features can be used in cell phones or other wireless communication devices, including automotive applications.Type: GrantFiled: July 18, 2011Date of Patent: November 26, 2013Assignee: Airbiquity Inc.Inventor: Michael Hirano

Patent number: 5896425Abstract: A method synchronizes a remote unit to a base station in a bandwidth efficient communication system and includes generating a clock signal at the base station. The clock signal is spread over a plurality of non-uniformly spaced discrete tones, thus creating a synchronization signal at the base station, which is transmitted from the base station and received at least one remote unit. Matched filtering is performed on the synchronization signal at the remote unit and the remote unit generates a remote clock signal synchronized with the synchronization signal, based on the matched filter output.Type: GrantFiled: February 24, 1997Date of Patent: April 20, 1999Assignee: AT&T Wireless Services IncInventors: Michael Hirano, Gregory J.
