Claim 12:
13. The method of claim 11, wherein estimating the fountain coded sequence from the feedback signal using a minimum mean square error receiver comprises estimating the fountain coded sequence according to the formula:

[{tilde over (s)}0,{tilde over (s)}1, . . . ,{tilde over (s)}N-1]=[r0,r1, . . . ,rm]G*(GG*+1/ρ)−1 

where rm denotes an mth element of the received signal, G denotes a generation matrix that comprises an N×M matrix comprising elements cn,m, N denotes a number of antenna branches of the plurality of antenna branches, M denotes a number of received symbols of the fountain coded sequence, m denotes the mth symbol of the fountain coded sequence on branch n of the N number of branches of the plurality of antenna branches, {tilde over (s)}n denotes an estimated value of the mth symbol of the fountain coded sequence on branch n, and ρ is signal-to-noise ratio (SNR).
