A bit sequence X1N is output by using X1N=D1NFN, where D1N is a bit sequence obtained after an input bit sequence u1N is encoded based on locations of K to-be-encoded information bits in an encoding diagram that has a mother code length of N, u1N is a bit sequence obtained based on the K to-be-encoded information bits, and FN is a Kronecker product of log2 N matrices F2. A design considers that the locations of the K to-be-encoded information bits in the encoding diagram that has a mother code length of N include a row location index set H of the information bits in the encoding diagram and a layer location index set M of the information bits in the encoding diagram, where 0≤H≤N, and 0

Abstract: A direct current (DC)/DC conversion circuit includes an input end, a power circuit, and an output end, a bypass circuit that is a unidirectional conduction circuit, and a switch disposed between the input end and the power circuit, where the input end is configured to be coupled to an external power supply to receive power to the DC/DC conversion circuit. The bypass circuit is coupled between the input end and the power circuit, the bypass circuit is disposed between the switch and the power circuit, and the bypass circuit is coupled to the power circuit in parallel. The switch is configured to be closed when the input end is reversely coupled to the external power supply to enable a current from a positive electrode of the external power supply to flow back to a negative electrode of the external power supply through the bypass circuit and the switch.
