摘要： A receiver and a receiving method for receiving wideband binary-offset-carrier modulated signals. The receiver includes a tracking apparatus which includes an upper sideband processor operable to generate upper sideband correlations through correlating a local upper sideband replica against a received navigation signal, a lower sideband processor operable to generate lower sideband correlations through correlating a local lower sideband replica against the received navigation signal, and an estimator operable to determine a delay estimate based on the upper sideband correlations and the lower sideband correlations.

摘要： The application relates to a generating method and device, receiving method and device for a dual-frequency constant envelope multiplexed signal with four spreading signals. According to the method, the four baseband spreading signals s 1 (t), s 2 (t), s 3 (t), s 4 (t) can be modulated to a frequency f 1 and a frequency f 2 respectively, so as to generate the constant envelope multiplexed signal on a radio carrier frequency f P = (f 1 + f 2 )/2, where the signals s 1 (t) and s 2 (t) are modulated on the frequency f 1 with carrier phases orthogonal to each other, the signals s 3 (t) and s 4 (t) are modulated on the frequency f 2 with carrier phases orthogonal to each other, f 1 > f 2 . The method comprises: determining a power ratio allocated to the four baseband spreading signals s 1 (t), s 2 (t), s 3 (t), s 4 (t) in the constant envelope multiplexed signal; storing an additional phase lookup table, wherein the table includes additional phases of an in-phase baseband component I(t) and a quadrature-phase baseband component Q(t) of the constant envelope multiplexed signal; obtaining an additional phase θ of a segment of the current time by looking up the additional phase lookup table; and generating an in-phase baseband component I(t) and a quadrature-phase baseband component Q(t) of the constant envelope multiplexed signal, and generating the constant envelope multiplexed signal S RF ( t ) based on the obtained additional phase θ.
