Data transfer systems Multiple Access Time Division Multiplexing

摘要

data transmission system with multiple access and time division channels contains n = 2k, where k2 - integer; j = 1, 2,...n is the number of the transmitting part, a base station) to transfer parts of user stations and the reception part of the central station in each transmitting part ab u043eu043du0435u043du0442u0441u043au043eu0439 station sequentially connected to the source of the information u0444u043eu0440u043cu0438u0440u043eu0432u0430u0442u0435u043bu044c information signal, u0444u043eu0440u043cu0438u0440u043eu0432u0430u0442u0435u043bu044c coded signal, u0444u043eu0440u043cu0438u0440u043eu0432u0430u0442u0435u043bu044c si u0433u043du0430u043bu043eu0432 double frequency u043cu0430u043du0438u043fu0443u043bu00a0u0446u0438u0438, u043cu043eu0434u0443u043bu00a0u0442u043eu0440,the transmitter and u043fu0435u0440u0435u0434u0430u044eu0449u0430u00a0 antenna, a clock pulse generator, connected to the u0442u0430u043au0442u043eu0432u044bu043c u0432u0445u043eu0434u0430u043c u0445u0440u043eu043du0438u0437u0430u0442u043eu0440u0430, u0444u043eu0440u043cu0438u0440u043eu0432u0430u0442u0435u043bu00a0 information signal u0444u043eu0440u043cu0438u0440u043eu0432u0430u0442u0435u043bu00a0 coded signal, u0444u043eu0440u043cu0438u0440u043eu0432u0430u0442u0435u043bu00a0 double frequency signal generator u043cu0430u043du0438u043fu0443u043bu00a0u0446u0438u0438, u043fu0441u0435u0432u0434u043eu0441u043bu0443u0447u0430u0439u043du044bu0445 numbers and synth frequenciessolution u0445u0440u043eu043du0438u0437u0430u0442u043eu0440u0430 jointly connected to the u0443u043fu0440u0430u0432u043bu00a0u044eu0449u0438u043c u0432u0445u043eu0434u0430u043c u0444u043eu0440u043cu0438u0440u043eu0432u0430u0442u0435u043bu00a0 information signal and information source, n u0443u043fu0440u0430u0432u043bu00a0u044eu0449u0438u0445 exits the generator u043fu0441u0435u0432u0434 u043eu0441u043bu0443u0447u0430u0439u043du044bu0445 numbers where n2, are connected to the respective (n u0443u043fu0440u0430u0432u043bu00a0u044eu0449u0438u043c u0432u0445u043eu0434u0430u043c synth frequency output which is connected to the u043cu043eu0434u0443u043bu0438u0440u0443u044eu0449u0435u043cu0443 entrance u043cu043eu0434u0443u043bu00a0u0442u043eu0440u0430 and u043fu0440u0438u0435u043cu043d u0430u00a0 part central station contains a reception antenna.the exit of which is connected to the information u0434u0435u043cu043eu0434u0443u043bu00a0u0442u043eu0440u0430 entrance, exit u0434u0435u043cu043eu0434u0443u043bu00a0u0442u043eu0440u0430 is connected to the selector signals, first, second, third, and fourth information u0446u0438u043eu043du043du044bu0435 exits which are connected respectively to the first, second, third and fourth information u0432u0445u043eu0434u0430u043c block u0432u044bu0434u0435u043bu0435u043du0438u00a0 additional follower duties,the first and second information exits the block u0432u044bu0434u0435u043bu0435u043du0438u00a0 additional sequences are connected respectively to the first and second information u0432u0445u043eu0434u0430u043c p u0435u0440u0432u043eu0433u043e u0434u0432u0443u0445u043au0430u043du0430u043bu044cu043du043eu0433u043e coherent filter, first and second information exits which are connected respectively to the first and second information. s first u0432u044bu0447u0438u0442u0430u0442u0435u043bu00a0,solution a first u0432u044bu0447u0438u0442u0430u0442u0435u043bu00a0 is connected to the first receiver information, a clock pulse generator, connected to the u0442u0430u043au0442u043eu0432u044bu043c u0432u0445u043eu0434u0430u043c synth frequency and generator u043fu0441u0435u0432u0434u043eu0441u043bu0443u0447u0430u0439u043du044bu0445 numbers (n u0443u043fu0440u0430u0432u043bu00a0u044eu0449u0438u0445 exits the generator u043fu0441u0435u0432u0434u043eu0441u043bu0443u0447u0430u0439u043du044bu0445 numbers are connected to the respective (n u0443u043fu0440u0430u0432u043bu00a0u044eu0449u0438u043c u0432u0445u043eu0434u0430u043c synth frequency output which is connected to the u043cu043eu0434u0443u043bu0438u0440u0443u044eu0449u0435u043cu0443 entrance u0434u0435u043cu043eu0434u0443u043bu00a0u0442u043eu0440u0430,u043eu0442u043bu0438u0447u0430u044eu0449u0430u00a0u0441u00a0, added n = 2k (where j = n + 1, n + 2,...the number of the transmitting subscriber station;
