In the first scenario, the DFE is based on feeding back previously estimated symbols from one particular antenna at a time.
The bits on each spatial stream are interleaved and mapped to symbols from one of the allowed -ary constellations (BPSK, QPSK, 16-QAM, or 64-QAM).
In one scenario, only previously estimated symbols from one transmit antenna are fed back to cancel/reduce ISI in the data stream of that particular transmit antenna.
In addition, if one of the two transmitted SSD symbols are not received correctly at the opposite terminal in the proposed SSC-2W scheme, it will still be able to recover both symbols from one SSD symbol due to the SSD technique.
Using the extra degrees of freedom offered by the MIMO system, a DFE that feeds back the previously estimated symbols on all data streams to cancel/reduce ISI on a particular data stream can be obtained, which is shown to outperform the linear MMSE equalizer and the DFE that feeds back only the previously estimated symbols from one particular data stream.
Each node broadcasts a signal constellation symbol, x u), from one of its available antennas.
So far, Ms. Clinton is more a character than a presence in the campaign, which seeks to portray Senator Clinton as a strong yet nurturing force, a friend to women and children and a symbol of progress from one generation to the next.

The pairing of digit and symbol was kept constant during the study, but the order in which the digits were presented in the list to be completed with symbols was different from one testing time to the next.
