摘要： A wireless communications device, e.g., a mobile node supporting direct peer to peer communications, performs a self-calibration of one or more of: receiver IQ imbalance, transmitter IQ imbalance, receiver DC offset, and transmitter DC offset. The wireless communications device, operating in calibration mode, intentionally sets the oscillator frequency used for downconversion in its receiver module to a different frequency than the oscillator frequency used for upconversion in its transmitter module. A first baseband signal, e.g., a single tone test signal, is input to the transmitter module and an upconverted transmit signal is generated. The transmit signal is routed via a feedback loop to the receiver, which performs a downconversion operation. Power and/or phase measurements of the signals output from the downcoversion are used to determine IQ imbalance compensation information and DC offset compensation information. The determined compensation information is used subsequently when operating in a communications mode of operation.

摘要： A communications device, e.g., a mobile wireless terminal, includes a plurality of antennas having different polarization directions. The plurality of antennas includes a first antenna and second antenna which are operated in a coordinated fashion. During reception a signal received via the first antenna is subjected to a phase shift operation before being combined with a signal received via the second antenna. During transmission a signal to be communicated is subjected to a phase shift operation and the phase shifted signal is transmitted over the first antenna while the non-phase shifted signal is transmitted over the second antenna. The amount of phase shift is a function of the difference in polarization directions between the first and second antennas. The novel antenna configuration facilitates the use of the horizontal polarization direction communications between the communications device and a base station without the need for directionally positioning one or more electrical antennas.

摘要： Methods and apparatus which support the use of differently polarized antennas to schedule two or more users employing multiple antennas with different polarization, on the same communications segment, e.g. a time/frequency slab, in either the uplink or downlink are described. Various embodiments include an access node which classifies and schedules wireless terminals to segments as a function of suitability for single polarization direction communications. Some embodiments are directed to methods and apparatus for operating a communications device supporting the use of multiple antennas having different polarization, to implement a polarization based multiple access scheme. Unlike Spatial Division multiple access schemes, the users sharing a communications segment in the polarization based scheme need not be geographically well separated. Another advantage of using the proposed method is that the communications system does not necessarily have to use a complex minimum mean square error receiver or implement successive iteration cancellation techniques, thereby reducing cost and system complexity.

摘要： Systems and methodologies are described that facilitate utilizing power-based rate signaling for uplink scheduling in a wireless communications system. A maximum nominal power (e.g., relative maximum transmit power that may be employed on an uplink) may be known to both a base station and a mobile device. For example, the base station and the mobile device may agree upon a maximum nominal power. According to another example, signaling related to a maximum nominal power for utilization on the uplink may be provided over a downlink. Further, selection of a code rate, modulation scheme, and the like for the uplink may be effectuated by a mobile device as a function of the maximum nominal power. Moreover, such selection may be based at least in part upon an interference cost, which may be evaluated by the mobile device.

摘要： The intonation of speech is modified by an appropriate combination of resampling and time-domain harmonic scaling. Resampling increases (upsampling) or decreases (downsampling) the number of data points in a signal. Harmonic scaling adds or removes pitch cycles to or from a signal. The pitch of a speech signal can be increased by combining downsampling with harmonic scaling that adds an appropriate number of pitch cycles. Alternatively, pitch can be decreased by combining upsampling with harmonic scaling that removes an appropriate number of pitch cycles. The present invention can be implemented in an automated speech-therapy tool that is able to modify the intonation of prerecorded reference speech signals for playback to a user to emphasize the correct pronunciation by increasing the pitch of selected portions of words or phrases that the user had previously mispronounced.
