IP3 2021-Wireless 1 (LOT 13070)

This lot is generally related to OFDM networks. Disclosed are techniques to perform least square (LS) equalization on an OFDM signal which makes full use of channel state information (CSI), improves performance and requires minimal and simple calculations. The technique receives a modulated signal, demodulates by using fast Fourier transform (FFT) and processes FFT demodulated signal. The technique further processes channel estimator output signal to produce a CSI signal and decodes the CSI aided LS equalized signal. The technology may be implemented in OFDM networks, ultra-wideband devices, wireless networks, mobile communication networks, cellular networks, network switches, modems, routers, base stations, etc.
