摘要： A system for signal processing is provided. The system includes a steady state processing system for receiving a signal. A general purpose processing system is coupled to the steady state processing system and includes a signal acquisition system for receiving the signal and generating acquisition data. The steady state processing system can receive the acquisition data from the signal acquisition system and use the acquisition data to acquire the signal.

摘要： A digital AGC system for burst operation, particularly suited for receiving packets in a wireless local area network. One embodiment includes a log detector that provides a signal strength measure, called the received signal strength indication (RSSI) over a wide dynamic range. The AGC system includes estimating the power in a received signal by averaging the log of the signal power. The Start of Packet detection avoids using the radio receiver's main analog to digital converters to preserve power.

摘要： A method, apparatus, and carrier medium for determining channel state information (CSI) in an OFDM radio receiver. The receiver is for receiving packets of OFDM data as a result of OFDM data being transmitted. The method includes forming an estimate of the channels of the subcarriers for received OFDM data to provide frequency responses of the channels of the subcarriers, and forming a measure of quality (“channel state information,” “CSI”) for the channels of the subcarriers based on the relative strength of the frequency responses. The forming of the CSI does not require estimating the relative amount of noise or interference in each channel. The formed CSI is used in demodulating and decoding received OFDM data.
