摘要： Systems and methods for time synchronization of orthogonal frequency-division multiplexing (OFDM)-based communications are disclosed. A cyclic prefix (CP) correlation-based timing synchronization method is disclosed for early path (e.g. first-received path) detection for OFDM-based communication. Systems and methods are disclosed for performing double peak value detection in an OFDM-based system for reliably detecting an early (e.g., first-received) path in a received OFDM symbol for use in timing synchronization. In the double peak value detection method, a first peak value detection is performed to detect the path with the largest power, and a second peak value detection is then performed to detect a desired early (e.g., first-received) path. A compensation linear curve is used to facilitate the second peak value detection.

摘要： This disclosure describes systems, methods, and devices related to enhanced validation of video codecs. A device may receive validation results for a video codec using a first computer programming language, the validation results indicative of invocations of functions and conditions of the code; identify, from the validation results, a first validation test that invoked a first function or condition of the code; identify, from the validation results, a second validation test that invoked the first function or condition of the code; determine, from the validation results, that the first validation test and the second validation test overlap in invoking the first function or condition of the code using the first computer programming language; and generate, based on the overlap, a first subset of the validation tests with which to validate code of the video codec using a second computer programming language.
