On the training of MIMO-OFDM channels with least square channel estimation and linear interpolation

The effect of pilot arrangement is investigated on the performance of trained MIMO-OFDM channels where fading is time-flat in a block of coherence-time duration but frequency-selective. The MIMO-OFDM channel is considered to be trained by using least square channel estimation on pilot subcarriers an...
