摘要： In a method for generating a data unit for transmission via a communication channel, wherein the data unit conforms to a first communication protocol, a preamble of the data unit is generated. The preamble includes a first field having information that indicates a duration of the data unit, the first field being formatted such that the first field is decodable by a receiver device that conforms to a second communication protocol but does not conform to the first communication protocol to determine the duration of the data unit based on the first field. Additionally, the preamble is formatted such that a portion of the preamble is decodable by a receiver device that conforms to a third communication protocol but does not conform to the first communication protocol. Also, the preamble is formatted such that a receiver device that conforms to the first communication protocol can determine that the data unit conforms to the first communication protocol. A data portion of the data unit that conforms to the first communication protocol and does not conform to either (i) the second communication protocol or (ii) the third communication protocol is generated.

摘要： A simplified architecture is disclosed for use in wireless receiver applications, particularly for ADC conversion of received in-phase I and quadrature Q signals. Circuit area is substantially reduced by sharing a single ADC to convert both signals, switching the ADC input alternately between the i and q signals. In an embodiment, the ADC is clocked at an increased sample rate, and the digital output signals are aligned to compensate for the phase difference resulting from the implementation of a single ADC.
