Definitions
- An advantage of the invention is that a radio communication method is provided that communicates even under strong narrow-band interference. So a stacked-carrier spread spectrum (SCSS) link can be maintained in the presence of strong narrow-band frequency- division multiple access (FDMA) and time-division multiple access (TDMA) cellular radio signals, as in cellular overlay applications. It also allows such a link to be maintained in the presence of spurious interference due to harmonics from out-of-band signals.
- SCSS stacked-carrier spread spectrum
- An advantage of the invention is that a radio communication method is provided that can be used with adaptive antenna arrays.
- Fig. 3B is a block diagram representing another embodiment of the invention wherein a stacked-carrier multiple-access transmitter is connected to a time-division duplexer for a network transmitter, and another time-division duplexer is connected to a stacked-carrier multiple-access receiver for a network receiver;
- Fig. 16 is a dataflow diagram representing a code-gated SCORE spreading operation with gating over two cell subsets, and demonstrates a symmetry with that of Fig. 15;
- Fig. 17 is a time-frequency format for a time-division duplex communication system embodiment of the invention;
- Fig. 28 is a dataflow diagram representing a cross-SCORE niequation with K part subsets
- Fig. 29 is a dataflow diagram representing a cross-SCORE niequation with two cell subsets
- Fig. 30 is a dataflow diagram representing a multi-link code-gated cross-SCORE spreader embodiment of the invention
- Fig. 35 is a dataflow diagram representing a single-link code-gated auto-SCORE despreading with gating over time and a rate one-half of redundancy gate.
- This invention can further be represented in various ways, e.g., by the several combinatorial embodiments illustrated in Figs. 2A-6B.
- Figs. 2A-6B Each of the major elements introduced in Figs. 2A-6B are described in further detail in connection with Figs. 7-16.
- the antennas in each array can have arbitrary spatial placement, e.g., the array does not require a special antenna geometry in order to function correctly.
- the antennas can be displaced in polarization as well as space.
- Fig, 2B shows a network transmitter 42 comprising a stacked-carrier multiple-access (SCMA) transmitter bank 44 connected to a multi-element antenna array (AA) 46.
- a network receiver bank 48 comprises a multi-element antenna array (AA) 50 connected to a stacked- carrier multiple-access (SCMA) receiver bank 52.
- a symbol encoding at the baseband tones is included in the baseline system 300.
- Each K ceH data bit modulates a separate tone in the signal baseband, such that a tone is phase modulated by O or 180° if the data bit modulating that tone is equal to zero or one, respectively.
- tone modulation is highly efficient in terms of allowable transmit power. It offers a vulnerability to radiometric detection techniques, and it allows reliable demodulation of the transmitted bit sequences at E,/N 0 of as low as three dB.
- the BPSK format allows for the use of powerful and sophisticated methods to remove timing and carrier offsets from the despread signal, when based on the conjugate self-coherence of the tone phase sequence.
- the retrodirective mode embodied in Figs. 6A and 6B as retro-adapters 136 and 148, is useful in applications where interceptors are placed in the same location with the interference sources, e.g., in order to assess the effectiveness of the jamming strategy. This strategy is most useful in underloaded environments where broadband nulls can be directed at the interference sources.
- Point-to-point as well as point-to-multipoint communication links, have increased user capacity, range, power and/or cost efficiencies that exceed those for full channel preemphasis methods.
