A method of soft bit metric calculation with direct matrix inversion MIMO detection

摘要

telecommunications MIMO receiver MIMO detection and direct matrix inversion with a soft bit metric calculation for implementation . A detector for detecting the data symbols of the received signal by the receiver determines the distance between the received signal point of the constellation (constellation) point ; The distance scale using a scaling factor (scaling) of the scaler ; And using the accumulated distance comprises soft bit metrics calculation for calculating an accumulated soft bit metrics (metics). The receiver may further comprise a decoder for decoding soft bit metrics so as to determine the data value of the received signal . The receiver , it is preferable to include also a quantizer to quantize the soft bit metrics dynamically before decoding by the decoder .
