Abstract: Devices and methods of compensating for a bandpass filter are generally described. A DTx includes a BPF from which an output signal is produced and a DFE having a zero crossing (ZC) pre-distorter (ZCPD). The ZCPD compensates for ZC distortion from a desired analog signal caused by the BPF. The ZCPD adjusts a DTC code word to generate a DTx output signal to be applied to the BPF. The compensation is dependent on a magnitude of the square wave immediately prior to and after the ZC. The compensated DTC and a DPA code word are used to generate the DTx output signal. The compensation produced by the ZCPD is free from compensation for non-linear responses to the DTC and DPA code words.

Abstract: A digital polar transmitter arrangement having a digital front end (DFE) and a transmit chain is disclosed. The DFE is configured to resample a baseband signal relative to a carrier frequency at a carrier frequency related sample rate, calculate zero crossing positions of the resampled signal, generate delay to time converter (DTC) commands based on the zero crossing positions, calculate amplitude values for the zero crossing positions and generate dynamic phase alignment (DPA) commands based on the amplitude values. The transmit chain is configured to generate an output signal having amplitude and phase modulation based on the DTC and DPA commands.

Abstract: 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.

Abstract: 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.
