Claim 7:
8. A baseband chip for wireless communication, comprising:
a memory; and
at least one processor coupled to the memory and configured to:
receive a data stream associated with a channel, the channel including a plurality of transmission layers, the plurality of transmission layers including first and second transmission layers associated with a resource block (RB), the RB including at least one reference resource element (RE) and a plurality of data resource elements (REs);
perform an initial noise estimation of the channel based at least in part on the reference RE;
perform a first noise whitening operation for the channel based at least in part on the initial noise estimation;
perform, for the RB, a first iteration of a recursive tree search operation for each of the plurality of data REs to determine a first symbol estimate associated with the first transmission layer; and
perform a subsequent noise estimation of the channel based at least in part on the reference RE, the plurality of data REs, and the first symbol estimate associated with the first iteration of the recursive tree search.
