Abstract

método para reduzir o tempo de guarda de um sistema em rede específico móvel (manet), e, sistema em rede específico móvel (manet). a presente invenção é direcionada para um método para reduzir o tempo de guarda de um sistema de rede específico móvel (manet) durante recepção, de acordo com o qual uma arquitetura de transceptor que é fornecida em cada nó, inclui uma combinação de um transmissor de salto e uma pluralidade de receptores de salto independentes de banda estreita que são capazes de receber e processar toda a banda operacional designada para o sistema, de uma vez, e que inclui frequências de canal selecionadas de maneira dinâmica dentro de uma largura de banda operacional larga. alternativamente, a arquitetura de transceptor inclui um receptor de banda larga não de salto, capaz de receber e processar de uma vez toda a banda operacional designada para o sistema. diversos canais dispersados de maneira arbitrária sobre uma banda de frequência designada para o sistema são recebidos de maneira simultânea enquanto mantendo a arquitetura do sistema manet. os padrões de salto de transmissão são determinados para utilizar o número mínimo possível de frequências. para cada nó de transmissão, intervalos de tempo nas quais um receptor de contrapartida em cada nó ativo remanescente não está transmitindo, e um canal de frequência no qual nenhum outro nó ativo transmite, são encontrados. a frequência de transmissão é então determinada e se nenhum outro nó escolheu um mesmo intervalo de tempo e se o transceptor não está transmitindo na faixa, a transmissão é recebida enquanto permitindo nós de relé transmitirem de maneira simultânea utilizando canais diferentes. sempre que uma pluralidade de receptores independentes de banda estreita é utilizada para recepção, tempo de guarda é alocado a intervalos de tempo sob demanda. de outra maneira, nenhum tempo de guarda é alocado para os intervalos de tempo.method to reduce the guard time of a system in a specific mobile network (manet), and system in a specific mobile network (manet). the present invention is directed to a method for reducing the guard time of a specific mobile network (manet) system during reception, according to which a transceiver architecture that is provided in each node, includes a combination of a transmitter of hop and a plurality of independent narrowband hop receivers that are capable of receiving and processing the entire operating band designated for the system at once and that include dynamically selected channel frequencies within a wide operating bandwidth . alternatively, the transceiver architecture includes a non-hop wideband receiver capable of receiving and processing all of the operating bandwidth assigned to the system at once. multiple channels dispersed arbitrarily over a frequency band designated for the system are received simultaneously while maintaining the architecture of the manet system. transmission hopping patterns are determined to use the minimum possible number of frequencies. for each transmitting node, time intervals in which a counterpart receiver in each remaining active node is not transmitting, and a frequency channel in which no other active node transmits, are found. the transmission frequency is then determined and if no other node has chosen the same time interval and if the transceiver is not transmitting in band, the transmission is received while allowing relay nodes to transmit simultaneously using different channels. whenever a plurality of independent narrowband receivers are used for reception, guard time is allocated to time slots on demand. otherwise, no guard time is allocated for the time slots.
