摘要：
The present invention provides a folded low-complexity (FLC) pipeline. In one embodiment, the FLC pipeline includes a dot product unit chain configured to employ only addition and multiplication operations to compute intermediate numerators and denominators from a received signal matrix, a channel gain matrix and a noise matrix. Additionally, FLC pipeline also includes a divider stage configured to terminate the dot product unit chain by computing an unscaled quotient and a scale factor from ultimate ones of the intermediate numerators and denominators.
