Abstract:
1. A power-saving method for Viterbi decoder of a wireless receiver, comprising the steps of: determining at least one numerical value related to a data rate applied by the wireless receiver while receiving packet; and deciding a duty cycle of the Viterbi decoder based on the at least one numerical value, wherein power is provided to the Viterbi decoder based on the duty cycle, wherein the step of determining at least one numerical value is to determine at least one factor among the group of number of bit per subcarrier (N wherein the step of determining at least one numerical value is to calculate a product of at least two of the number of bit per subcarrier (N wherein the step of deciding the duty cycle comprises the steps of: calculating and producing a maximum product from all possible products of the number of bit per subcarrier (N calculating a ratio (r) between the product of the at least two of the number of bit per subcarrier (N
