| 20120106525 | MOBILE WIRELESS COMMUNICATIONS DEVICE HAVING A SINGLE BLUETOOTH / WIRELESS LOCAL AREA NETWORK ANTENNA AND ASSOCIATED METHODS - A mobile wireless communications device includes a wireless local area network (WLAN) radio configured to generate a WLAN transmit signal, and a Bluetooth radio configured to generate a Bluetooth transmit signal. A circulator is coupled downstream of an antenna. A transmit path couples the WLAN radio and the Bluetooth radio to the circulator such that the WLAN radio and the Bluetooth radio are capable of transmitting simultaneously. In addition, a receive path also couples the WLAN radio and the Bluetooth radio to the circulator such that the WLAN radio and the Bluetooth radio are capable of receiving simultaneously. | 05-03-2012 |

| 20110222636 | METHOD AND RECEIVER FOR ESTIMATING THE CHANNEL IMPULSE RESPONSE USING A CONSTANT MODULUS INTERFERENCE REMOVAL ITERATION - A receiver and associated method estimates a channel impulse response of the communications signal. A communications signal is received as a burst of transmitted symbols, including a known training sequence. The joint estimation of timing offset and initial channel impulse response is determined based on the cross-correlations of the known transmitted symbols and received communications signal. A constant modulus interference removal iteration is applied to improve the initial channel impulse estimation. | 09-15-2011 |
| 20110195696 | COMMUNICATIONS SYSTEM INCLUDING AGGREGATION SERVER FOR DETERMINING UPDATED METADATA OF E-MAIL MESSAGES AND RELATED METHODS - A communications system includes a mobile wireless communications device and an e-mail server configured to store pushed e-mail data and metadata associated therewith already pushed to the mobile wireless communications device. An aggregation server is configured to download a first set of metadata of pushed e-mail data at a first time, and generate and store a first set of hash values corresponding to the first set of metadata. The aggregation server is also configured to download a second set of metadata of pushed e-mail data at a second time after the first time, and generate and store a second set of hash values corresponding to the second set of metadata. The aggregation server is further configured to determine an updated set of metadata based upon a comparison of the first and second sets of hash values, and push the updated metadata to the mobile wireless communications device. | 08-11-2011 |
