Abstract: A preamble channel encoder, e.g., in a UHDR-DO system, uses a channel structure that can efficiently transmit more information bits, yet achieve sufficient detection and false alarm performance. The preamble channel encoder uses tail-biting convolutional coding and Cyclical Redundancy Check (CRC). The preamble channel structure can be used to encode, e.g., rate indicator bits, while a MAC identifier encoder, e.g., a Reed-Solomon encoder, is used to encode MAC identifier bits. The encoded rate indictor and MAC identifier bits can then be mapped to the appropriate tones in an OFDM encoding scheme.

Abstract: A mixing unit includes a baseband signal processing unit, a radio frequency (RF) signal processing unit and a mixing unit. The baseband signal processing unit receives or generates a baseband signal. The RF signal processing unit processes or outputs a RF signal. The mixing unit is coupled to the baseband signal processing unit and the RF signal processing unit to select and operate in an up-convert mode or a down-convert mode according to a control signal. When the mixer operates in an up-convert mode, the mixing unit mixes the baseband signal with a local oscillation signal to generate the RF signal and outputs the RF signal to the RF signal processing unit. When the mixer operates in a down-convert mode, the mixing unit mixes the RF signal with the local oscillation signal to generate the baseband signal and outputs the baseband signal to the baseband signal processing unit.

Abstract: A wireless communication system including a receiver and a transmitter. The receiver receives a frame of data, and sends an acknowledgement. The acknowledgement includes a positive acknowledgement (ACK) if the data is successfully decoded or a negative acknowledgement (NAK) if the data is unsuccessfully decoded. The acknowledgement is sent according to timing of an acknowledge mask. The transmitter is wirelessly coupled to the receiver, and receives the acknowledgement according to the acknowledge mask, and sends a response to the receiver according to the acknowledgement. The response includes, if an ACK is received before transmission completes of the frame, the transmitter terminates transmission of the frame; if a NAK is received before transmission completes of the frame, the transmitter continues to send the frame; and if an ACK is not received before a predefined frame early scheduling point, the transmitter retransmits the frame after transmission completes of the frame.
