Triangular Memory Polynomial Predistorter
2009 5th International Conference on Wireless Communications, Networking and Mobile Computing, 2009To predistort a power amplifier nonlinear with memory effects, a triangular memory polynomial (TMP) predistorter is presented based on the traditional memory polynomial predistorter. The coefficients of the predistorter can be directly extracted from an offline system identification process using an open-loop structure.

Polynomial Trend Regression With Long‐memory Errors
Journal of Time Series Analysis, 2005Abstract. For a time series generated by polynomial trend with stationary long‐memory errors, the ordinary least squares estimator (OLSE) of the trend coefficients is asymptotically normal, provided the error process is linear. The asymptotic distribution may no longer be normal, if the error is in the form of a long‐memory linear process passing ...

Certification of Safe Polynomial Memory Bounds
2011In previous works, we have developed several algorithms for inferring upper bounds to heap and stack consumption for a simple functional language called Safe. The bounds inferred for a particular recursive function with n arguments takes the form of symbolic n-ary functions from (R+)n to R+ relating the input argument sizes to the number of cells or ...

An Memory polynomial model for power amplifiers
2008 International Conference on Communications, Circuits and Systems, 2008In this paper, an envelope Memory polynomial (MP) model is introduced to describe dynamic input -output characteristics of RF power amplifiers. In the modeling approach, we use a new truncation method and an established nonlinear time series method to determine model structure.

Theoretical Characterization of Memory Polynomial Models With Gaussian Inputs
IEEE Signal Processing Letters, 2009We consider distortion of a Gaussian signal by a memory polynomial system and prove a theorem about a linear representation of the output. As an application example, we analyze an OFDM system with a nonlinear high power amplifier at the transmitter.

Memory polynomial predistorter based on the indirect learning architecture
Global Telecommunications Conference, 2002. GLOBECOM '02. IEEE, 2003Power amplifiers (PAs) are inherently nonlinear devices and are used in virtually all communications systems. Digital baseband predistortion is a highly cost effective way to linearize PAs, but most existing architectures assume that the PA has a memoryless nonlinearity. For wider bandwidth applications such as WCDMA, PA memory effects can no longer be

Polynomial-time algorithm for on-chip scratchpad memory partitioning
Proceedings of the international conference on Compilers, architectures and synthesis for embedded systems - CASES '03, 2003Focusing on embedded applications, scratchpad memories (SPMs) look like a best-compromise solution when taking into account performance, energy consumption and die area. The main challenge in SPM design is mapping memory locations to scratchpad locations.

IEEE Transactions on Circuits and Systems I: Regular Papers, 2013
This paper proposes a new three-layered biased memory polynomial for behavioral modeling and digital predistortion of highly nonlinear transmitters/power amplifiers (PAs) for 3G wireless applications. The proposed model considers the possibility that the nonlinearity order of the dynamic part of the PA characteristics is different from the nonlinearity

2009 International Conference on Communications, Circuits and Systems, 2009
Power amplifiers (PAs) are inherently nonlinear devices and are used in all transmitters of a communications equipment. To improve the performance of telecommunication channels, digital baseband predistortion is employed to compensate for PA nonlinearities. But most existing architectures base on the memoryless PA model.
