摘要： A frequency specific receiver and method can receive a transmitted polarized carrier signal wave, the carrier signal wave having a carrier frequency, encoding one or more data bits, includes a synchronization filter to determine a reference time at 0π of the carrier signal wave from a forward wave received at a forward antenna element and a rear wave received at a rear antenna element, positioned apart from one another by a distance of ¼ wavelength of the transmitted carrier signal wave and oriented in a polarization direction of the transmitted carrier signal wave. A first A/D converter samples the forward wave at π/2, π, 3π/2 and 2π radians and a second A/D converter samples the rear wave at π/2, π, 3π/2 and 2π radians. A control processor decodes a value of the encoded data bit by calculation of an average computation and a calculation of a correlation computation.

摘要： A stream of modulation symbols from a zero symbol rate (ZSR) coding/modulation module and a stream of modulation symbols from another type of coding/modulation module are input into an interweaver module. The interweaver module mixes the two input streams when assigning modulation symbols to be communicated in a segment. If a ZSR modulation symbol is non-zero, the ZSR modulation symbol is allocated a transmission position. If the ZSR modulation symbol is a zero modulation symbol, the modulation symbol from the other coding/modulation module is allocated the transmission position. The non-zero modulation symbols from the ZSR module are higher in power than the non-zero modulation symbols from the other module, thus facilitating detection and recovery.
