Abstract: Dynamic characterization of complex high-order nonlinearity in transmitter (TX) and receiver (RX) signal chains of transceiver systems can be efficiently and accurately performed. A loopback connection may be used to facilitate self-characterization. Appropriate RX and TX configuration settings may be developed to facilitate de-coupling of individual RX and TX nonlinearities from measured cascade nonlinearity. The system's high-order response to a two-tone signal generation may be measured, and complex mathematical analysis may be performed to identify and isolate passband nonlinear components to extract a high-order memory-less model for the system. The extracted system model may be used in the corrective and non-iterative pre-distortion of generated signals and in the post-distortion of received signals to improve linearity performance of the transceiver.

Abstract: System and method for compiling a program, including determining one or more program structures containing one or more variables at the entry and exit of each program structure, wherein each variable specifies a value transfer operation of one or more source variables to a destination variable between outside the program structure and inside the program structure. A subset of the destination variables may be determined for which assigning the destination variable to a memory resource of a corresponding source variable does not disrupt the functionality of the program. Implementation of the value transfer operations may be executable to map each of the determined subset of destination variables to a respective memory resource. The mapping may be dynamically changed, thereby transferring the value from the first source variable to the destination variable without copying the value between the memory resources.
