Abstract:
-
We introduce bootstrapping as a generic method for
improving channel equalization in TDMA cellular systems where the
channels remain approximately constant over a transmitted burst.
Bootstrapping implies that the detection is repeated, using
an equalizer tuned with detected symbols. The procedure can be
iterated to achieve even better performance.
The initial equalizer is assumed to be tuned using a short known training
sequence. When applied to experimental data from a DCS-1800 antenna
array testbed, bootstrap equalization yields a performance improvement
of 14 dB for a space-time maximum likelihood sequence detector and 17
dB for a space-time decision feedback equalizer in an interference
limited scenario.
