"Low Complexity Estimation of Frequency Selective Channels for the LTE-A Uplink";
IEEE Wireless Communications Letters,
3GPP LTE-A uplink channel estimation is based on
pilot symbols. For the support of MIMO transmissions, a special
reference symbol structure was standardized to perform MIMO
channel estimation without excessive overhead. We propose a low
complexity channel estimation method in the frequency domain
based on correlation that exploits the orthogonal structure of the
reference symbols to mitigate inter-layer interference. Further, we introduce a smoothing method to deal with the interference
that leads to improved performance at low signal to noise ratio.
