Patent number: 9088314Abstract: A method is provided for reducing the peak power level in a combination of orthogonal frequency division multiplexed (OFDM) tones. The method is particularly effective when the information to be communicated is digital data consisting of long patterns of “1”s or “0”s. The digital data of the message is combined with a scrambling vector before the data is modulated. The randomization of data patterns, in turn, leads to a more random combination of OFDM tone amplitude being transmitted. The message is recovered at the receiver by removing the scrambling vector. An OFDM communication system using the above-described method is also provided.Type: GrantFiled: April 21, 2014Date of Patent: July 21, 2015Assignee: AT&T Mobility II LLCInventors: Salvador Garcia, Jr., Eamonn Gormley, Elliott Hoole

Patent number: 8358632Abstract: A method for accessing a reverse channel for communication from a remote unit to a base station is disclosed. The method includes waiting a random period of time in response to determining that the reverse channel is available at a first time. The method also includes monitoring a forward channel after expiration of the random period of time to determine whether the reverse channel is available at a second time. The method further includes transmitting a first portion of data on the reverse channel in response to determining that the reverse channel is available at the second time.Type: GrantFiled: December 28, 2009Date of Patent: January 22, 2013Assignee: AT&T Mobility II LLCInventors: Kevin M.
