Channel estimation filter normalization |
摘要 |
Disclosed are various embodiments providing processing circuitry for selecting a channel estimation filter from a plurality of channel estimation filters based on a channel quality metric, the selected channel estimation filter being associated with an intrinsic coefficient. The processing circuitry may then determine a scaled coefficient, the scale coefficient being based on scaling the intrinsic coefficient with respect to a bit size constraint, the bit size constraint being determined by a bit length of a multiplication circuitry operand. Moreover, the processing circuitry may generate an output based on the scaled coefficient and an input signal. |

1. A method for a processing circuit comprising:
selecting a channel estimation filter from a plurality of channel estimation filters based on a channel quality metric, the selected channel estimation filter being associated with an intrinsic coefficient, wherein a scaled coefficient of the selected channel estimation filter is based on scaling the intrinsic coefficient with respect to a bit size constraint, the bit size constraint being determined by a bit length of a multiplication circuitry operand; initializing the selected channel estimation filter with input history of a previously selected channel estimation filter; and generating an output based on the scaled coefficient and an input signal. |
