Time diversity combining to increase the reliability of the receiver IEEE802.11WLAN

摘要

A method and system for synthesizing a signal in a receiver. If it is determined in accordance with criteria default when there is a packet that the current packet is re-transmitted, the signal is computed from the preamble of each packet is erroneous packet previously stored in the packet number and the same packets retransmitted is synthesized using a maximum ratio combining method (SNR) follow-noise ratio. In the case of diversity synthesis of this type, while the data packet reliable transmission in a short time can be obtained, SNR increases, throughput time in a multi-path channel is reduced.
