摘要： To provide an extra bandwidth communication using standard channels, multiple non-overlapping channels (301, 302) can be used. To provide a 40 MHz communciatio, two non-ovrlapping 20 MHz channels (301,302), i.e. a control channel (301) and an extension channel (302), can be used to provide an effective 40 MHz channel. Advantageously, a wireless device can dynamically detect 20/40 MHz signals on a packet-by-packet basis, thereby facilitating commercially viable 40 MHz communciation. The wireless device can monitor traffic on the extension channel to facilitate accurate 20/40 MHz decision making. Protection, e.g. legacy preambles (311) and RTS/CTS headers (321, 322,...), can be provided on the control (301) and extension (302) channels.

摘要： An accurate total error rate performance can be measured using a computed error vector magnitude (EVM) per stream. Using this EVM, the receiver or the transmitter can advantageously generate an optimized modulation and coding scheme (MCS) that corresponds to a specific number of streams, modulation and coding rate for the transmitter. For example, the receiver can compute an SNR from the EVM and then use an SNR vs. MCS table to determine the optimized MCS. In contrast, the transmitter can receive an EVM-to-RSSI mapping and an EVM- to-MCS mapping from the receiver. These mappings and an EVM can facilitate selecting the optimized MCS.
