System-level evaluation of space-time processing for EDGE

Decoupled Space-Time Processing for Eqialization and Co-Channel Interference Cancellation in Mobile Communication Systems

“…It was verified that the proposed D-ST receivers have superior performance as compared to its conventional counterparts in scenarios limited by lSI and CCI. As shown in [24] such link-level gains offered by the D-ST can be translated into throughput gains at the system-level as well as higher user capacity.…”

“…In [24] we have shown that such link-level gains offered by the D-ST strategy can be translated into throughput gains at the system-level.…”

“…the first optimization criterion under the UTC approach to adapt the D-ST receivers, since it has provided good results under different equalizer options and scenarios [22][23][24]. For evaluation of the bit-error-rate (BER) performance of the D-ST receiver structures we use the channel model suggested by COST 259 recommendations [25].…”

A Space-Time Multi-User Detector with Decoupled Processing for Wireless Communications

“…Additionally, in high-speed mobile communication services channel frequency selectivity induces inter-symbol interference (ISI) on the received signals. In order to cope with the simultaneous presence of CCI and ISI in single-carrier systems, and to keep a satisfactory bit-error-rate (BER) performance, several space-time signal processing techniques have been developed in the last years [1][2][3][4][5][6][7][12][13][14]. Most of them are based on combinations of array processing and temporal equalization.…”

“…The above space-time processing approaches were generalized in [12][13][14][15][16] to cope with other equalizer structures and have been called decoupled space-time (D-ST) processing. In its more general meaning, the term decoupled accounts for the fact that interference cancellation and equalization are divided in two processing stages.…”
