Other Controls

• Generates a received data vector of specified symbol length, corresponding to the current parameter settings.
• Is specified in symbols. If the spreading code is 31 and the chosen Length of Received Data is 1000, then the received data will be contained in a vector of length 31*1000.
    
  Figure 4.5: (a) In-Cell user power distribution (b) In-Cell user delay distribution (c) and cross correlation of user 3's spreading code with other in-cell users at zero delay. This figure was generated from the System Parameters window by choosing View Properties.
  
    
  Figure 4.6: (a) Channel Impulse response of user 3 (b) pulse shaping filter (c) and frequency response of user 3's channel. This figure was generated from the System Parameters window by choosing View Properties.
  

• Graphically represents the properties of the user specified by View User. The properties that are represented are
  • power of in-cell users
  • relative delay of in-cell users
  • Cross Correlation of View User's spreading code with the other in-cell users at delay zero,
  • channel impulse response of View User
  • pulse shaping filter
  • channel frequency response of View User
  Examples of the plots generated from View Properties are shown in figures 4.5 and 4.6.
• Calls the control window responsible for saving and loading the system parameters. See section 4.3.3.
• Closes the system parameters window. As a result, the changes you have made to the default parameters will be lost unless you saved them before pressing Done. The received vector and necessary information for simulating the detectors is not affected. Therefore, you can still run simulations once you have closed the System Parameters window.
• This window informs you if you have made an invalid parameter choice, or when received data is being generated, or if parameters have been changed since you last generated data.
• The six random seed buttons control the seeds used to generate the respective components. If you want to generate the same data every time, then click these to the off position. Otherwise, leave them in the default position of 'on'.
