Method And Apparatus For Estimating Frequency Offset And Timing Offset Of One Or More Mobile Stations

View page
US Patent:
8139667, Mar 20, 2012
Filed:
Nov 22, 2010
Appl. No.:
12/951185
Inventors:
Rajesh Raja Manakkal - Santa Clara CA, US
Louay Jalloul - Santa Clara CA, US
Sam P. Alex - Santa Clara CA, US
Anupama Lakshmanan - Santa Clara CA, US
Djordje Tujkovic - Santa Clara CA, US
Sriram Mudulodu - Santa Clara CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
H04L 27/28
US Classification:
375260, 375219
Abstract:
A method and apparatus for estimating frequency offset and timing offset of a first Mobile Station (MS) in a communication system is provided. The method includes receiving a composite signal at a plurality of receiver antennas of a Base Transceiver Station (BTS). The composite signal includes a first signal transmitted from a first MS and a second signal transmitted from a second MS. The composite signal includes one or more tiles. Each tile includes a plurality of data sub-carriers, a plurality of first pilot sub-carriers, and a plurality of second pilot sub-carriers. A total phase offset of the first MS is estimated based on a complex conjugate product of pilot symbols of the plurality of first pilot sub-carriers. Thereafter, a first phase offset corresponding to the timing offset of the first MS is estimated based on a Power Delay Profile (PDP) of one or more first pilot sub-carriers. Finally, a second phase offset corresponding to the frequency offset of the first MS is determined based on the total phase offset and the first phase offset.

US Patent:
8295775, Oct 23, 2012
Filed:
May 1, 2008
Appl. No.:
12/150862
Inventors:
Louay Jalloul - Santa Clara CA, US
Djordje Tujkovic - Santa Clara CA, US
Anupama Lakshmanan - Santa Clara CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
H04B 17/00
US Classification:
455 6711, 455434, 455436, 455437
Abstract:
A method and apparatus of determining a hand-off metric is disclosed. One method includes a subscriber receiving identifications of a neighboring set of base stations from a serving base station. From the neighboring set, the subscriber determines an active set of base stations. The active set is determined by the subscriber measuring received signal power from each of the base stations of the neighboring set at first discrete points in time, averaging the received signal power for each of the base stations of the neighboring set, and selecting the active set based on the average received signal power of the base stations of the neighboring set. Determining the at least one hand-off metric further includes the subscriber measuring at second discrete points in time an excess received signal power for each base station of the active set, wherein the excess received signal power includes signal power received by the subscriber in excess of power received from the base station. The subscriber averages the excess received signal power. The subscriber calculates the hand-off metric by calculating a ratio of average receive signal power to average excess received signal power, for each base station of the active set.
