Abstract: A method, an apparatus and a computer program product for enhancing reception of signals in a wireless communication system. A signal containing a frame including a plurality of symbols is received on an uplink communication channel. An angular position of at least one symbol in the plurality of symbols in a constellation of symbols is detected. The plurality of symbols include equalized symbols. An angular difference corresponding a phase error between the detected angular position of the symbol and an expected reference angular position in the constellation of symbols corresponding to an expected reference symbol corresponding to the received frame is determined. Using the determined phase error, a phase of the symbol is compensated.

Abstract: Methods, systems, and computer program products are provided for enhancing detection in wireless communication systems. In some implementations, one or more symbol separations between one or more symbols in a plurality of symbols can be identified across one or more antennas receiving a signal including a frame having the plurality of symbols on a communication channel. The plurality of symbols can include one or more symbol groups. One or more correlation metrics can be determined for at least one symbol group in the one or more symbol groups using the identified one or more symbol separations. Based on the determined one or more correlation metrics, one or more carrier frequency offsets associated with the signal received by the one or more antennas can be generated.

Abstract: Methods, systems, and computer program products are provided for enhancing detection in wireless communication systems. In some implementations, a signal received by one or more antennas on a communication channel can be processed. The signal can include a frame having a plurality of symbols, and the plurality of symbols can include one or more symbol groups. A signal to interference noise power ratio (SINR) associated with the received signal can be determined using a signal power determined based on subcarrier resource allocation and noise power determined based on one or more reserved subcarrier allocation associated with the received signal.
