OFDM Channel Estimation in the Presence of Interference
Abstract
We develop a frequency-domain channel estimation algorithm for single-user orthogonal frequency division multiplex (OFDM) wireless systems in the presence of interference. In this case, the received measurement is correlated in space with covariance matrix dependent on frequency. Hence, the commonly used leastsquares algorithm is suboptimal. On the other hand, accurate estimation of the spatial covariance matrix in such a model using the …
