摘要： A method for correcting I/Q imbalance in a received signal is disclosed. The method includes the steps of grouping (202) the received signal into a predetermined number of clusters, and determining (204) at least one coefficient value by feeding the predetermined number of clusters into a nested loop. The method further includes computing (206) a compensation value based on the at least one coefficient value, and correcting (208) the I/Q imbalance in the received signal by using the compensation value.

摘要： A communication device receives control information during transmission of streaming data, such as speech data, over a wireless channel (300). The communication device identifies a portion of the streaming data, such as representing a pause in speech, as compressible data or white space data (310, 320). Continuous transmission of the streaming data is interrupted to request and receive control information on the wireless channel, using the channel space made available by not transmitting the identified portion of data or by transmitting it in a more compressed format (330, 340).

摘要： A radio device requires a tunable transceiver such that the transceiver can be accurately set to a desired frequency. When a signal with known frequency accuracy is being received, an offset detector can determine the frequency offset generated by the transceiver due to improper tuning. An automatic frequency control (AFC) system (100) is comprised of a tunable transceiver, an offset detector (103) and an AFC control processor (105) for utilizing information from the offset detector to reduce the inaccuracy in frequency by tuning the transceiver towards the received signal frequency. The AFC control processor (105) utilizes one of more threshold levels for defining a maximum correction threshold (311) based upon the desired maximum offset correction. These thresholds are used by the AFC control processor (105) to efficiently control the predetermined frequency range of the tunable transceiver (101) for most efficient operation.

摘要： A sweatband for a hat, that can be easily inserted and removed, comprising a flexible retaining strip which permanently attached on one end to the inside surface of a hat, with the opposite end of the strip removably attached to the inside surface of the hat by means of a snap fastener, and a tubular sweatband, which, when the snap fastener is disengaged, can be inserted around the retaining strip, and thereby be retained in the hat when the snap fastener is engaged. The sweatband can also be easily removed to be cleaned or replaced by unfastening the removable end of the retaining strip.
