signlms

#signlms function for Scilab

What is it?

This function creates an AdaptiveAlgorithm Object for Signed Least Mean Square Algorithm to use it with lineareq or dfe to create an equalizer object.
This function has been developed for Communication toolbox in Scilab under Project FOSSEE Toolbox.

Usage

• Change current directory to path/to/function/.
• In Scilab prompt, run: exec('signlms.sci'). This will load the function in environment.
  The function is tested on Scilab 5.5.2. There is no specific OS requirement.

Instructions

alg = lms(stepsize, alg_type, leakage_factor)

• Input Arguments:

  • stepsize : Any non-negative real number. It is StepSize parameter for LMS algorithm.
  • alg_type : Select algorithm from a set of signed LMS algortihms.
    Options: 'Sign LMS' (default), 'Signed Regressor LMS', 'Sign Sign LMS'
  • leakage_factor : Real number between 0 to 1. It is Leakage Factor parameter for LMS algorithm. (Default = 1)

• Output:

  • alg : Adaptive Alagorithm Object based on Input parameters. Implemented as a Structure type.

Example

alg = signlms(0.1, 'Sign Sign LMS')

Output:

alg  =
   AlgType: "Sign Sign LMS"
   StepSize: 0.1
   LeakageFactor: 1
