FIELD: physics, radio.
SUBSTANCE: invention is related to device and method for coding of block code of low density parity check (LDPC). Substance of invention consists in the fact that during reception of information word vector coder codes vector of information word into block code of LDPC in compliance with preset generating matrix. Modulator modulates block code LDPC into modulation symbol using preset modulation pattern. Transmitter sends modulation symbol.
EFFECT: provision of decoding reliability with minimization of LDPC block code coding complexity.

METHOD FOR TRANSMISSION OF DISCRETE INFORMATION (RU2348102)
» Order full text of this Russian patent (in Russian)
» Order translation of this Russian patent
FIELD: physics, radio.
SUBSTANCE: invention is related to radio communication and may be used in systems for transmission of discrete information that function in unfavourable noise environment. Method provides introduction of redundancy into initial binary sequence (BS) on transmitting side, and on receiving side – introduction of initial BS restoration. Redundancy is introduced by generation of ternary code symbols that carry information on position of current bit in block of zeros or block of units. If symbol of ternary code defines odd position of bit in block of units or in block of zeros, then carrying oscillation is modulated by parameter that differs by value for block of units and block of zeros. If it defines even position – then by the third value. The first two values of parameter carry information about unit and zero accordingly. The third value – about repetition of initial BS current bit. Arriving signals are demodulated by method that corresponds to type of modulation. Values of modulation parameters are defined. Symbols of ternary code are restored by values of parameters. For this purpose every symbol of ternary code is transformed into three bits, from bits of appropriate positions three BS are formed. Units of the first and second BS correspond to bits of initial BS that occupy odd positions. Units of the third BS correspond to bits that occupy even positions. Using bits of the first two BS initial BS is restored. Bits of the third BS serve for synchronisation of reception process.
EFFECT: increase of throughput capacity of radio communication lines and simplicity of realisation.

(54) FILTER ON SURFACE ACOUSTIC WAVES
FIELD: physics, radio.
SUBSTANCE: invention is related to radio electronics, in particular, to frequency selective facilities, and may be used in devices of radio signal frequency selection. Grounded bus of double-mode resonator communication is arranged in the form of meander, at that value of intersection between neighbouring pins (aperture W) periodically changes, taking two values: W1 (minimum) and W 2 (maximum). Since interaction between symmetrical and antisymmetrical modes in this case is more intense than in prototype, filter passband is increased up to 0.15%.
EFFECT: increase of relative passband.
