Abstract: The present disclosure describes apparatuses and methods for implementing a reinforcement learning-enabled low-density parity check (LDPC) decoder. In aspects, an RL-enabled LDPC decoder processes, as part of a first decoding iteration, data of a channel to generate LDPC state information and provides the LDPC state information to a machine learning (ML) algorithm of an RL agent. The RL-enabled LDPC decoder is then configured with LDPC decoding parameters obtained from the ML algorithm and processes, as part of a second decoding operation, the data using the decoding parameters to generate subsequent LDPC state information. The RL-enabled LDPC decoder provides decoded data of the channel based on the subsequent LDPC state information. By using the LDPC decoding parameters provided by the ML algorithm of the RL agent, the RL-enabled LDPC decoder may decode channel data in fewer decoding iterations or with a higher success rate, thereby improving LDPC decoding performance.

Abstract: A device includes a voltage regulator circuit, a power switch circuit, and a control circuit. The voltage regulator circuit generates an output voltage at an output terminal. The power switch circuit is coupled to the voltage regulator circuit. The control circuit receives a first control signal and generates a second control signal that includes a first portion gradually declining between a first time and a second time later than the first time. When the voltage regulator circuit is turned off and a logic state of the first control signal changes at the first time, the power switch circuit is turned on at the second time, in response to the second control signal, to adjust the output voltage.

Abstract: An electronic device may have transparent housing structures such as walls formed of glass or sapphire. Housing structures such as transparent housing structures may have a colored coating. The colored coating may include an absorptive layer and a metal layer. The coating may exhibit a color that can be adjusted by adjusting the thickness of the thin absorptive layer. A colored layer such as a layer of colored polymer may be incorporated into the colored coating to further adjust the color of the coating. The colored coating may be formed on an inner or outer housing structure surface. The surface may have a texture to provide the coating with a matte appearance. When formed on an outer surface, a diamond-like carbon layer may protect the colored coating. When formed on an inner surface, a passivation layer may be used to prevent oxidation of the metal layer.

Abstract: Provided are a VOIP terminal and a ringing parameter setting method therefor. An application scenario detecting module of the VOIP terminal detects an application scenario of the VOIP terminal, and sends a detection result to a parameter matching module of the VOIP terminal, the parameter matching module matches a ringing parameter according to the detection result, and then a parameter setting module of the VOIP terminal sets the VOIP terminal according to the ringing parameter obtained by the matching. Manual setting according to experience is not involved. The set ringing parameter can better meet requirements of various voice user terminals under the VOIP terminal compared with an existing manual setting manner. Abnormal conditions that some voice user terminals ring briefly all the time, some voice user terminals are muted after ringing a sound, even some voice user terminals have no ringing all the time, and so on under the same VOIP terminal can be reduced, and user experience can be improved.
