Neste artigo, propomos um novo método para coletar informações de detecção usando um sinal ortogonal de banda estreita para detecção cooperativa em rádio cognitivo. É desejável melhorar o desempenho da detecção do espectro contrariando o efeito de localidade de um canal sem fios; a detecção cooperativa usando múltiplas entradas de informações de detecção dos nós de detecção circundantes atraiu a atenção. A detecção cooperativa requer que as informações de detecção sejam coletadas no nó mestre para determinar a existência de um sinal primário. Se o método de recolha de informação utilizado conduzir a redundâncias, a capacidade total das redes secundárias não será melhorada. Neste artigo, propomos um novo método para coletar informações de detecção que mapeia as informações de detecção para o sinal de banda estreita ortogonal para obter a coleta simultânea de informações de detecção no nó mestre. Neste método, a informação de detecção é mapeada para um sinal de subportadora ortogonal de uma estrutura de multiplexação por divisão de frequência ortogonal (OFDM) para reduzir o recurso de frequência necessário para a coleta de informação de detecção. Os sinais ortogonais são transmitidos simultaneamente de vários nós sensores. Este artigo avalia o desempenho do método de coleta de informações proposto e confirma sua eficácia.

Abstract: In this paper, we propose a novel method for gathering sensing information by using an orthogonal narrowband signal for cooperative sensing in cognitive radio. It is desirable to improve the spectrum sensing performance by countering the locality effect of a wireless channel; cooperative sensing by using multiple inputs of sensing information from the surrounding sensing nodes has attracted attention. Cooperative sensing requires that sensing information be gathered at the master node for determining the existence of a primary signal. If the used information gathering method leads to redundancies, the total capacity of the secondary networks is not improved. In this paper, we propose a novel method for gathering sensing information that maps the sensing information to the orthogonal narrowband signal to achieve simultaneous sensing information gathering at the master node. In this method, the sensing information is mapped to an orthogonal subcarrier signal of an orthogonal frequency division multiplexing (OFDM) structure to reduce the frequency resource required for sensing information gathering. The orthogonal signals are transmitted simultaneously from multiple sensing nodes. This paper evaluates the performance of the proposed information gathering method and confirms its effectiveness.
