Optimization of all software modem using flexible configuration parameters for high-performance computing (hpc)

Abstract

A method to provide flexibility on the configuration and operation of the modulator, demodulator, and modem, where purpose-built (legacy) devices are not traditionally capable of exposing a level of control and flexibly for a user or an autonomous program for optimizing performance. Providing user or programmatic control of algorithms is traditionally not possible for purpose-built modems. Parameters such as the number of decoder iterations that are performed on Forward Error Correction (FEC), Interference Mitigation algorithm, or dynamic adjustment loop bandwidth to combat phase noise can be adjusted autonomously to optimize receiver performance. The all software modem, supported by a High-Performance Computing (HPC) architecture, removes the limitation due to the flexibility of programming resources and available performance. Unlike most purpose-built hardware, the HPC allows processing resources to dynamically be reallocated, so that as additional performance is desired, the resources may be increased and decreased as required.
