摘要： A method and apparatus for channel estimation in wireless communications are provided. After an initial channel estimation and an estimation of the effective channel length (ECL) are performed, a weighting based on the ECL may be applied in an effort to remove noise from the initial channel estimate and provide an estimated channel with increased accuracy. Different weightings may apply for different channel lengths. A threshold may be used during the ECL estimation, and the threshold may be predetermined or calculated in an effort to adapt to different channel environments.

摘要： In accordance with a detection method in a wireless communication system, an initial hypothesis for a starting position of a desired signal within a received wireless communication signal may be determined. The desired signal may have a conjugate symmetric property. At least one correlation value may be determined based on the initial hypothesis. The at least one correlation value may indicate the extent to which at least one sample sequence selected from the received signal has the conjugate symmetric property.

摘要： Techniques for initial wireless network synchronization by a mobile station are provided. For certain embodiments, the techniques may involve a joint search for the cell identification (ID-cell index) and the coarse carrier frequency offset (CFO) estimation. For certain embodiments, the techniques may be based on hard correlation and binary differential despreading that substantially simplifies computational complexity compare to known techniques that independently search for the ID-cell index and perform CFO estimation.

摘要： A multichannel multitrack audio system and an audio processing method are provided. The audio processing method down-mixes and encodes a first audio object constituting the audio from multiple channels to a lower number of channels. Thus, the method for down-mixing audio objects of the audio from the multichannel to the lower number of channels generates the multichannel multi-object audio and reproduces the generated multichannel multi-object audio. Abrupt data increase can be addressed in processing the multichannel multi-object audio.

摘要： A method and apparatus for combining retransmitted hybrid automatic repeat-request (HARQ) messages divided into coding blocks in an orthogonal frequency-division multiplexing (OFDM)/orthogonal frequency-division multiple access (OFDMA) receiver are provided. According to such a coding-block-based HARQ combining scheme, the quality of each coding block may be compared to a threshold to determine whether the decoded bits or the HARQ combined signal should be saved for each coding block for subsequent HARQ iterations. In addition to reducing the required HARQ buffer size while preserving the combining gain, coding-block-based HARQ combining may also provide fast decoding and reduced power consumption when compared to conventional HARQ combining techniques.
