Multi-transmitter channel estimation for a time varying channel

A method of performing multi-transmitter channel estimation for a time-varying channel, wherein the method includes:

• (a) wirelessly receiving at least two frames, each frame including a block of training symbols received at different points in time for a time-varying channel;
• (b) estimating, for each block at a block location, a first channel coefficient of the time-varying channel, wherein the block location is the same for each block;
• (c) interpolating or extrapolating a plurality of second channel coefficients for the respective training symbols of each block based on the respective first channel coefficient;
• (d) re-estimating the first channel coefficient for each block based on the plurality of second channel coefficients for each block;
• and
• (e) re-estimating the plurality of second channel coefficients for each block by interpolation or extrapolation using the respective first channel coefficient.
