Method for increasing the performance of a communications system on a medium formed by multiple conductors which increases the performance of a communications system by means of the creation of numerous communication channels with a high degree of isolation between each other on the same physical medium formed by multiple conductors. The method can be extended to be used in various applications, such as the reuse of frequencies on the same channel, the increase of the capacity of the point-to-point links in a network and the improvement of performance and reliability when used with digital processing of signals for transmission or reception, among others.

Method for increasing the performance of a communications system on a medium formed by multiple conductors

This method reduces the variance of the estimation of the signal-to-noise rate in a multiuser digital communications system. These communications require a sending of a phase reference symbol prior to sending a information, where the estimation is made of the signal-to-noise rate in order to use a modulation with a maximum number of bits per symbol, maintaining a bit error probability in reception within certain given margins. The method minimizes and equalizes the variance of the samples obtained for the different values, even and odd of bits per carrier, which the system uses. The estimation is necessary for selecting the number of bits per carrier in order to be adapted to the channel and as back-up information in the event of using a receiver with diversity.
