Abstract: Interpolation logic described herein provides a good approximation to a bicubic interpolation, which is generally smoother than bilinear interpolation, without performing all the calculations normally needed for a bicubic interpolation.

For a plurality of the predetermined interpolation positions which surround the sampling position, the corresponding sets of predetermined weights and the data points are used to determine a plurality of surrounding interpolated values which represent results of performing the bicubic interpolation at the surrounding predetermined interpolation positions.

Abstract: Systems, methods, and apparatuses are provided for detecting and potentially invalidating or correcting jump errors in data from growth processes. A jump error can be identified by determining a second derivative of the data set, and identifying two consecutive cycles with opposite signs in the second derivative. Once a jump error has been detected, the data set can be invalidated or corrected based on various criteria. Whether to invalidate or correct can be based on an absolute jump height, a relative jump height (e.g., relative to the net growth or relative to the baseline), an absolute location (cycle number) of the jump, or a relative location. In one implementation, the jump can be corrected by subtracting a jump height from points subsequent to the jump or by adding the jump height to points prior to the jump.

Abstract: Systems and methodologies are described that facilitate equalization of received signals in a wireless communication environment. Multiple transmit and/or receive antennas and utilize MIMO technology to enhance performance. A single tile of transmitted data, including a set of modulation symbols, can be received at multiple receive antennas, resulting in multiple tiles of received modulation symbols. Corresponding modulation symbols from multiple received tiles can be processed as a function of channel and interference estimates to generate a single equalized modulation symbol. Typically, the equalization process is computationally expensive. However, the channels are highly correlated. This correlation is reflected in the channel estimates and can be utilized to reduce complex equalization operations. In particular, a subset of the equalizers can be generated based upon the equalizer function and the remainder can be generated using interpolation. In addition, the equalizer function itself can be simplified.
