摘要： A reconfigurable baseband filter for use in a multimode communication system is disclosed. One or more filter elements (260), (270) can each be configured as a plurality of sub-elements (262, 264), (272, 274). The value of each of the filter elements can be varied by switching between at least two of the plurality of sub-elements. Switching noise within a desired passband can be reduced by switching at a rate that is greater than the desired passband. The switching noise in the passband can be further reduced by pseudo-randomly switching between the sub-elements. The filter can use a delta-sigma modulator to generate a pseudo-random switching signal.

摘要： Multiple wireless communication standards can be supported in a single radio apparatus by time interleaving communications with the multiple communication standards. A single radio can be controlled to time interleave communications standards to successively activate a single communication channel for each of the communication standards. The single radio device can be configured to order the supported communication standards in a hierarchy to provide priority to certain communications. Time interleaving wireless communications over standards that support burst communications, such as time multiplexed wireless communication systems or wireless packet data systems, allows a single radio to seamlessly support multiple with no loss of data.

摘要： A multi-mode wireless device having a transceiver including a multi-mode transmitter and a multi-mode receiver. The transmitter can include a multi-mode transmit baseband portion configured to support all of the transmit modes. Similarly, the receiver can include a multi-mode baseband portion that is configured to support all of the receive modes. The transmitter can also include a frequency conversion stage that can convert the modes, can selectively amplify the transmit signals. The receiver can include multiple low noise amplifiers (LNAs) in parallel, each configured to selectively amplify the received signals of one or more of the operating modes. The output of the LNAs can be coupled to a frequency conversion stage that downconverts the received signals and provides them to the baseband portion.

摘要： Methods and apparatus for synchronizing Wireless Local Area Network (WLAN) communication within a multi-mode radio. A multi-mode radio can support communication with a WLAN and at least one other wireless communication system. The multiple systems can be distinct and asynchronous. Transmitting, or attempting to transmit, over a WLAN communication link can result in interference that degrades the sensitivity of a receiver in another communication system, or that interferes with a transmission in another communication system. The WLAN transmissions can be synchronized to operation in another communication system by generating a signal that can be coupled to a collision avoidance system in the WLAN transmitter. The signal can operate to cause the WLAN transmitter to reschedule the transmission to another time such that the resources of the multi-mode radio are conserved and the WLAN interference is minimized.
