Abstract
Methods and systems are described for frequency domain correction, time domain correction, and combinations thereof. Each Long Term Evolution (LTE) uplink residual frequency offset can be determined with less than 1 part per billion accuracy simultaneously and used for frequency offset correction. The disclosed method utilizes the same modulated signals for data and control as the 3GPP LTE wireless standard and can be embedded directly into the base station (downlink) PHY without additional hardware. The use of the disclosed methods provide multiple ways to simultaneously improve the uplink data throughput for every user in an LTE multiple access wireless system.
