According to an aspect of an embodiment, a method of increasing efficiency of a software program may include executing a software program that is developed based on a dynamically-typed programming language. Thereafter, the soft-decision demodulated output words are de-interleaved and scaled, thereby producing de-interleaved and scaled words. In an exemplary system the communicating DEV may transmit a frame, which represents a physical layer PDU. A light source is optically coupled with the light path of the first face and a spectrometer is optically coupled with the light path of the second face.
