Patent ID: 7826560

Claim:
A wireless communication device comprising: a baseband signal processor configured with a plurality of signal processing function modules comprising: a symbol encoder configured to encode a bit sequence into a sequence of multidimensional symbol vectors; a symbol interleaver configured to interleave the symbol vectors so that elements of a vector are grouped together for transmission in a common one of a plurality of orthogonal bins and such that information transmitted within one bin does not substantially interfere with information transmitted in another bin; a plurality of transmit signal processors each of which being configured to assign elements of a symbol vector, after interleaved by the symbol interleaver, to a corresponding one of a plurality of antennas depending on the bin for the element of the symbol vector; and a transmit spatial processor that is configured to apply weights to outputs of the plurality of transmit signal processors so as to weight the elements of a symbol vector assigned to the respective bins according to a predetermined criteria, and to produce a plurality of antenna specific baseband transmit signals according to a plurality of transmit spatial directions determined by the weights.
