Abstract
The multi-configuration adaptive layered steered space-time coded (LSSTC) wireless transmission system utilizes Layered Steered Space-Time Codes (LSSTC), a recently proposed multiple-input multiple-output (MIMO) system that combines the benefits of the vertical Bell Labs space-time (V-BLAST) scheme, space-time block codes (STBC) and beamforming. A multi-configuration transmission scheme based on LSSTC and V-BLAST systems uses threshold-based decision making to change the modulation type and the MIMO transmission scheme in order to optimize error performance.
Claims3
A multi-configuration adaptive method applied by a transceiver in a layered steered space-time coded (LSSTC) wireless transmission system, the method comprising the steps of:
- receiving channel state information (CSI) and direction of arrival data (DOA) as a feedback signal at the transceiver;
- and
- automatically switching between a vertical Bell Labs space-time (V-BLAST) antenna array configuration and an LSSTC antenna array configuration and switching modulation mode based on signal-to-noise ratio (SNR) thresholds compared with the feedback signal in the wireless transmission system.
