Sparse channel estimation for OFDM system weighted l<sub>p</sub> norm

Sparse channel estimation for OFDM system weighted l<sub>p</sub> norm

The new lp norm was introduced to substitute the l<sub>0</sub> and l<sub>1</sub> norm,as they met some problems when used to estimate sparse channel in LMS algorithm.By analyzing the l<sub>p</sub> norm,the optimal value of p was obtained,it was 1/2.Then a most spa...
