摘要： A wireless repeater includes a receiver circuit implemented as an intermediate frequency (IF) subsampling receiver and a transmitter circuit implemented as a direct conversion (zero-IF) transmitter. The repeater further includes a reference receiver implemented as an IF subsampling receiver to sample a portion of the transmit signal prior to over-the-air transmission for use as the reference signal for channel estimation. Highly accurate channel estimation is obtained by using the reference signal from the reference receiver as the reference signal accounts for distortions in the transmitter circuit of the repeater. The repeater may include an echo canceller to cancel an estimated feedback amount from an input signal based on the channel estimation.

摘要： A wireless repeater has a receiving antenna for receiving an input signal and a transmitting antenna for transmitting an amplified signal where the input signal is a sum of a remote signal and a feedback signal. The repeater includes an echo canceller receiving the input signal and generating an echo cancelled signal by estimating a feedback channel between the transmitting antenna and the receiving antenna and cancelling a feedback signal estimate from the input signal, an amplifier for amplifying the echo cancelled signal and providing the amplified signal to the transmitting antenna, and a variable delay element receiving the echo cancelled signal and introducing a first delay to the echo cancelled signal. The first delay is selected to optimize the estimation of the feedback channel, thereby optimizing the cancellation of the feedback signal. The delayed echo cancelled signal is coupled to the echo canceller as a reference signal for estimating the feedback channel.

摘要： Techniques for facilitating the exchange of information and transactions between two entities associated with two wireless devices when the devices are in close proximity to each other. A first device uses a first short range wireless capability to detect an identifier transmitted from a second device in proximity, ideally using existing radio capabilities such as Bluetooth (IEEE802.15.1-2002) or Wi-Fi (IEEE802.11). The detected identifier, being associated with the device, is also associated with an entity. Rather than directly exchanging application data flow between the two devices using the short range wireless capability, a second wireless capability allows for one or more of the devices to communicate with a central server via the internet, and perform the exchange of application data flow. By using a central server to draw on stored information and content associated with the entities the server can broker the exchange of information between the entities and the devices.
