摘要： This application discloses a polar polar code interleaving processing method and apparatus. The method includes: determining N to-be-encoded bits, where N is a positive integer (S210); obtaining a first sequence that includes sequence numbers of N polarized channels, where the first sequence is used to indicate a reliability order of the N polarized channels (S220); performing polar encoding on the N to-be-encoded bits to obtain encoded bits (S230); and performing interleaving processing on the encoded bits based on the first sequence (S240). Because the first sequence used to indicate the reliability of the polarized channels is a sequence already existing in a polar code encoding process, no additional storage resource needs to be used to store the first sequence in the interleaving processing process, thereby reducing use of storage resources. In addition, interleaving processing is performed on the encoded bits based on the existing first sequence, so that implementation of interleaving processing is simple.

摘要： The present invention relates to a heat sink, including a base and a plurality of fins. A root of the fin is connected to the base. A heated area, a dropping pipe, and a spacing strip between the heated area and the dropping pipe are formed in the fin. A first passage and a second passage are formed between the heated area and the dropping pipe. The first passage and the second passage are located between the heated area and the dropping pipe. A hydraulic diameter of a pipeline in the heated area is less than a critical dimension, so that a working medium in the heated area is heated to form a gas-liquid plug flow flowing into the dropping pipe through the first passage. A hydraulic diameter of a pipeline of the dropping pipe is greater than or equal to the critical dimension, and a pressure of liquid at an intersection of the second passage and the dropping pipe is greater than a pressure of liquid at an intersection of the second passage and the heated area, so that liquid in the dropping pipe flows toward the heated area through the second passage. The heat sink in the present invention has an advantage of high heat dissipation efficiency. The present invention further provides a communications product.
