Abstract: Embodiments of the disclosure relate to reducing intermodulation distortion (IMD) in a radio frequency (RF) circuit. In examples discussed herein, the RF circuit operates in an uplink carrier aggregation (ULCA) mode to transmit an RF uplink signal simultaneously in a first uplink band and a second transmit band. However, nonlinear components in the RF circuit can create an IMD product(s) that can fall into a downlink band of an RF downlink signal, thus impairing a receive filter's ability to receive the RF downlink signal in the downlink band. The receive filter can be opportunistically reconfigured to form an IMD shunt path to attenuate the IMD product. By reconfiguring the receiver filter to form the IMD shunt path, it is possible to suppress the IMD product in the RF uplink signal, thus leading to an improved desense performance in the ULCA mode without incurring additional cost and/or battery life penalty.

Abstract: A method and apparatus for improving channel estimation within an OFDM communication system. Channel estimation in OFDM is usually performed with the aid of pilot symbols. The pilot symbols are typically spaced in time and frequency. The set of frequencies and times at which pilot symbols are inserted is referred to as a pilot pattern.
