The present invention discloses a wireless communication method for transceiving packets in wireless networks. The method comprises the steps of: transmitting a first packet with a first packet format, wherein a header of the first packet with the first packet format comprises information of a first communication duration; and performing a communication procedure during the first communication duration for transmitting at least one second packet with a second format, for receiving at least one third packet with the second format, or for both transmitting the at least one second packet and receiving the at least one third packet.

A method for enhancing Ethernet channel impairment comprises the steps of sending a sequence to a receiver in a slave transceiver by a master transceiver, and training cancellation filter coefficients of an echo canceller and a near-end cross talk canceller in the master transceiver before the receiver of the slave transceiver converges.

The method generates a candidate list in accordance with the contents of frames transmitted by access points and sequentially performs the handshaking operations with the access points on the candidate list to select a personal identification number (PIN) enabled access point. During the candidate list generating process, this method places Wi-Fi protected setup (WPS) PIN-enabled access points at high priority positions but eliminates non-WPS access points and WPS push button configuration enabled access points.
摘要:
A method for progressively scanning channels first checks whether all channel scanning tasks are completed so as to determine a channel that will be scanned first. During the scanning process, the method records a channel as a last scanned channel after completing a channel scanning task for the channel. In addition, the method scans a channel with a valid service set identifier to increase the possibility of detecting hidden access points.
摘要:
Instead of scanning all the channels at once, the present method separates a channel scanning procedure into multiple channel scanning operations. The method reduces a data loss rate during the operation by returning to the operating channel an associated access point operates on in accordance with a return period for transceiving blocked packets.

A method for selecting modulation and coding scheme (MCS) for multi-antenna systems comprises the steps of: a multi-antenna system transmits signals according to MCSs of single spatial stream and determines an MCS accordingly. Subsequently, the multi-antenna system increases the number of the spatial streams applied, transmits signals according to the corresponding MCSs and determines an MCS accordingly until an optimum MCS is found.
