摘要： A diagnostic system for an internal combustion engine includes an intake air temperature (IAT) determination module, a reference temperature determination module, and an adaptive learning module. The IAT determination modules determines a first IAT using an IAT sensor at a first time and determines a second IAT using the IAT sensor at a second time. The reference temperature determination module determines a first frequency based on a first voltage output of a MAF sensor at the first time and determines a second frequency based on a second voltage output of the MAF sensor at the second time. The adaptive learning module determines a temperature-frequency relationship based on the first IAT, the second IAT, the first frequency and the second frequency.

摘要： A multi-antenna codebook selection modulation method for solving weak scattering is provided by the present invention. The method obtains higher diversity gain from a combination of multi-antenna codebook pre-coding and a rotation modulation solution by designing a new codebook selection rule. The present invention employs a design solution of designing a higher-order modulation diversity and space interleaver to obtain the higher diversity gain. In addition, the number of transmission antennas and the number of rotation modulation dimension can be set arbitrarily. However, the present invention takes the number Nt of transmission antennas to be equal to the number D of rotation modulation dimension in order to obtain higher diversity gain. In this way, the method evenly disperses signals of each dimension after D-dimensional rotation to each antenna through space interleaving technique, so that the signals of each dimension suffer different fading, thus enabling space diversity gain. With the present invention, the data of a transmitting end are pre-coded by using a channel value estimated for an ideal channel.
摘要翻译：本发明提供了一种解决弱散射的多天线码本选择调制方法。该方法通过设计新的码本选择规则，从多天线码本预编码和旋转调制解决方案的组合中获得更高的分集增益。本发明采用设计高阶调制分集和空间交织器的设计方案来获得更高的分集增益。此外，发送天线的数量和旋转调制维数可以任意设定。然而，为了获得更高的分集增益，本发明使发送天线的数量Nt等于旋转调制维数D。以这种方式，通过空间交织技术，将D维旋转后的每个维度的每个维度的信号均匀地分散到每个天线，使得每个维度的信号具有不同的衰落，从而使得能够进行空间分集增益。利用本发明，通过使用为理想信道估计的信道值对发送端的数据进行预编码。
