Abstract
Certain embodiments of the present disclosure provide techniques for channel estimation without resorting to the channel second-order statistics. Methods and systems are proposed for improving the performance of an un-constrained least squares channel interpolator by using available side information of the channel, such as signal-to-noise ratio (SNR), Doppler frequency and/or delay spread.
