Abstract: A device and a method for mixed mode communication are disclosed. For example, a Bluetooth master device transmits data packets to a Bluetooth slave device and receives acknowledgments from the Bluetooth slave device, by controlling a transceiver to transmit the data packets based on a Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) protocol, and to receive the acknowledgements packet (ACK) based on a Bluetooth Low Energy (BLE) protocol. In another example, a Bluetooth slave device receives the data packets from a Bluetooth master device and transmits acknowledgments to the Bluetooth master device, by controlling a transceiver to receive the data packets based on a BR/EDR protocol, and to transmit the ACK based on a BLE protocol.

Abstract: A method and apparatus for synchronizing a wireless communication receiver such as a Bluetooth receiver, including estimating the condition of the communication channel and operating the receiver either in frequency domain mode or in time domain mode based on the channel condition estimation. A soft threshold is used to estimate the symbols of the access address code. Oversampled data rate received data is processed at symbol rate of the data. Receiver functions are terminated upon determining that no signal that the receiver can decode is being received. Synchronization includes a correlator that processes an entire address code or a correlator that processes the address code in segments.

Abstract: For example, a wireless communication device may be configured to determine a count of one or more unreliable data symbols in a received wireless communication packet having a valid Cyclic Redundancy Check (CRC) result; based on the count of the unreliable data symbols, to determine whether to classify the valid CRC result as a false-positive CRC result; and, based on classification of the valid CRC result as a false-positive CRC result, to handle the received wireless communication packet as having a non-valid CRC result.

Abstract: An arrangement for detection of multiple signals concurrently is disclosed. The arrangement includes a demodulator component, a mixer and a detector. The demodulator component is configured to demodulate or obtain one or more components from a received signal. The mixer is configured to mix the one or more components into a folded signal using a plurality of varied local oscillator (LO) signals. The detector is configured to identify a valid signal within the folded signal and to initiate a response for the identified valid signal.
