Abstract

Настоящее изобретение относится к способу кодирования и декодирования слабого сигнала, например тонального сигнала Бодо, для передачи в системе связи 100. Система связи 100 может содержать любое количество каналов беспроводной связи. После обнаружения в системе связи 100 слабого сигнала, предназначенного для передачи, каждый вокодер в системе 100, предназначенный для кодирования и декодирования сигналов, выполняет заданные операции кодирования или декодирования. В соответствии с одним из вариантов осуществления изобретения, кадры данных, содержащие ошибки, искажающие сигнал, передаются в вокодер, и программно заданные биты, содержащиеся в кадрах данных, используются для определения исходного сигнала. В соответствии с другим вариантом, сигнал кодируется в соответствии с алгоритмом избыточного кодирования, после чего сигнал, кодированный таким образом, вводится в кадры данных, передаваемые в вокодер.
