Abstract: Embodiments herein relate to a circuit for evaluating the ground voltage of each circuit partition of a number of circuit partitions, one partition at a time. Once the ground voltage is determined, a corresponding code is stored to control a leakage circuit coupled to the ground node. The leakage circuit provides a leakage current based on the code to offset the ground voltage to a target voltage, which may be common for each of the partitions. The circuit can include a voltage source which supplies a stair step increasing voltage to a comparator. The comparator compares the voltage of the voltage source to the ground node voltage and provides an output which changes when the two input voltages are approximately equal, within a tolerance. The circuit may include a finite state machine for managing the process.

Abstract: A method and an apparatus are provided in an OFDM receiver for detecting and compensating for long echo. The method comprises a first pilot tone interpolation mechanism and a first window placement to filter a received OFDM symbol, a long echo channel detection coupled with a second pilot tone interpolation mechanism, a pre-echo and post-echo detection wherein the pre-echo condition is associated with a second new window placement, and both pre-echo and post-echo conditions place two time windows around a first peak channel response and a second peak channel response for channel estimation. The long echo is estimated by obtaining power spectra of a subset of subcarriers in one OFDM symbol, performing an inverse Fourier transform on the power spectra and determining the long echo by measuring the time between two peaks in the power profile.

Abstract: A method for performing channel estimation of an OFDM channel includes, in part, interpolating pilots for sub-channels positioned within a first range of an OFDM symbol, and estimating frequency response of sub-channels positioned within a second range of the OFDM symbol. The first range is defined by subchannels positioned substantially away from channel edges and the second range is defined by subchannels positioned substantially near channel edges. The method optionally includes transforming the pilots from frequency domain into the time-domain, time-domain windowing to obtain a channel impulse response having a multitude of discrete values, estimating the discrete values within the channel impulse response; and transforming the channel impulse response to the frequency domain.

For 2k and 4k modes, the channel is estimated using the preceding symbol, the present symbol, and two succeeding symbols. For an 8k mode, only one future symbol is used to estimate the channel.

The list of transforms includes a data structure having a first stream that includes a map that correlates the stream with a name for the list of transforms. A second stream that lists each of the transforms for the stream. A third stream for each of the transforms listed that identifies information associated with the transform.
