    摘要: An antenna assembly, a receiver, and a system configured to superimpose a first received signal from a first antenna and an intermediate signal based on a second received signal from a second antenna onto a single cable. The antenna assembly includes a mixer and an adjustable local oscillator (ALO) that frequency shift the second received signal to generate the intermediate signal. The output frequency of the ALO is controlled by a control signal superimposed on the single cable that is output by the receiver. With this arrangement, a plurality of antennas or antenna elements can be connected to a receiver using a single coaxial cable. Such an arrangement is particularly desirable to manufacturers of automobiles and other vehicles. Also, the receiver can detect if the output frequency of the ALO needs to be adjusted, and so close-loop control of the output frequency is possible.

    摘要: The present invention provides a method, receiver and transmitter for use in a SDAR system. The method involves generating a first modulated signal based on first input data. Additional modulation is superimposed on the first modulated signal based on additional input data, being spread across a plurality of symbols in the first modulated signal in a predetermined pattern to generate a modified signal which is then transmitted. The modified signal is decoded by performing a first demodulation of the first modulated signal then additional demodulation is performed to obtain additional input data. The superimposing step uses a plurality of offset sequence values to add the additional modulation to the first modulated signal. The offset sequence may appear as a pseudo-random distribution of offset sequence values, and may include at least one zero offset value. Alternatively, the additional modulated signal may be a formed as a direct sequence spread spectrum modulation and the offset sequence appearing as a pseudo-noise distribution. A Hadamard matrix sequence may be used as the direct sequence code.
