    摘要: A channel decoder for a digital broadcast receiver having a synchronization byte detector for detecting synchronization bytes in a decoded transmission signal. The synchronization byte detector provides a synchronization signal indicating a start of frame for transport stream packets in the decoded transmission signal and provides a lock detected output signal indicating the lock-in of the receiver to one broadcast channel. The lock detected output signal is used as at least one of a feed forward signal and a feed back signal to switch processing stages at least one of succeeding and preceding, respectively, said synchronization byte detector into a different mode dependent on whether or not a lock has been achieved.

    摘要: The present invention relates to a device (10) for receiving signals in a wireless orthogonal frequency division multiplex (OFDM) system and to a channel estimation method in such a system. The data symbols and pilot symbols are transmitted in frequency subcarriers and timeslots, whereby pilot symbols are transmitted in a continuous stream within at least one frequency subcarrier. A channel estimation for a data symbol is performed on the basis of received pilot symbols using a filter including a common phase error correction value from the continuous stream pilot symbol in the same timeslot as the data symbol to be channel estimated.The present invention thereby enables a correct and efficient channel estimation including a common phase error correction to be performed.

    摘要: A method for recognizing speech is proposed wherein the process of recognition is started using the starting acoustic model (SAM) and wherein the current acoustic model (CAM) is modified by removing or cancelling model function mixture components (MFMjk) which are negligible for the description of the speaking behavior and quality of the current speaker. Therefore, the size of the acoustic model (SAM, CAM) is reduced by adaptation to the current speaker enabling fast performance and increased recognition efficiency.

    摘要: To avoid an over-adaptation of a current acoustic model (CAM) to certain and frequently occuring words for speech phrases during on-line speaker adaptation of speech recognizers it is suggested to count adaptation numbers (aj) for each of said speech phrases (SPj) as numbers of times in that a distinct speech phrase (SPj) has been used as a basis for adapting said current acoustic model (CAM) and further to make the strength of adaptation of the current acoustic model (CAM) on the basis of said distinct speech phrase (SPj) dependent on its specific adaptation number (aj) so as to decrease the influence of frequent speech phrases (SPj) in the received speech flow on the adaptation process.

    摘要: According to the present invention a system and a method for synchronising digital communication systems is proposed. Thereby a reference symbol RS consisting of a sequence of a plurality of synchronisation patterns SP and followed by data symbols, which are both modulated (13) on a RF-frequency is provided. The received reference symbol (RS) is correlated with a delayed version of itself and the correlation peak is identified giving the position and complex correlation result that can be used for the timing and frequency synchronisation of a digital communication system. According to the present invention the phase of the last and/or the first of the plurality of synchronisation patterns SP of said reference symbol RS (or a part or a multiple thereof) is phase shifted, e.g. by 180.degree., before the transmission step. According to the present invention therefore the effects of random contribution of adjacent data symbols of the reference symbol to a correlation calculation based on a synchronisation algorithm can be entirely eliminated. Through the inversion of the last synchronisation pattern and the reference symbol the correlation peak, which is used to determine the symbol timing, is offset inside the reference symbol. Thus, the precision of the timing error estimation is improved significantly.
