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.

Abstract: Described herein are technologies related to an implementation of interference mitigation in a receiver of a portable device. A preemptive-automatic gain control (AGC) system mitigates a collocated or external interfering signal in a receiver of a portable device. The receiver of the portable device receives and processes a data packet of a first radio frequency (RF) signal that includes a Bluetooth (BT) signal, a Wi-Fi signal, a near field communications (NFC), 3G, 4G, or the like. During the processing of the data packet, a collocated or an external second RF signal is detected and received by the receiver. The second RF signal includes an interfering Bluetooth (BT) uplink transmission, a near field communications (NFC) transmission signal, a Wi-Fi transmission signal, 3G or 4G uplink transmission, an LTE signal, or the like.

Abstract: Embodiments pertain to systems, methods, and component devices for Tx-Tx transmit concurrency by combining signals before power amplification. One example embodiment includes validity check circuitry configured to check a transmission power for a Bluetooth signal against a first threshold transmission power, a Bluetooth Power Amplifier, and a WLAN power amplifier. A switching network controlled by the validity check circuitry and configured to couple the Bluetooth input to Bluetooth power amplifier input when the transmission power for the Bluetooth signal is above the first threshold transmission power and to couple the Bluetooth signal with a WLAN signal for input to the shared WLAN power amplifier when the transmission power for the Bluetooth signal is less than the first threshold transmission power.
