  1. Quick start in SEAMCAT European Communications Office Jean-Philippe Kermoal (ECO) December 2009

  2. Creating - Opening - Saving a workspace (.sws) version Date of release new open save Select the .sws file

  3. Defining sharing study scenario iRSS dRSS Interfering Transmitter (It) Victim Receiver (Vr) Victim link Interfering link Wanted Receiver (Wr) Wanted Transmitter (Wt)

  4. Victim Link Parameters Victim receiver characteristics (non-CDMA systems) (sensitivity, BW, antenna, blocking response, interference criteria, etc...) General information on the link Wanted transmitter characteristics (non-CDMA systems) (power, antenna) Position and propagation model information between the Wt and the Vr Choice from a library Distribution of the dRSS Distribution of the center frequency

  5. Victim Link Parameters - CDMA system CDMA module Distribution of the center frequency Selection of the CDMA module Definition of the CDMA victim receiver blocking response

  6. Interfering Link Parameters Add/edit/ duplicate as many interferer as necessary Position and propagation model information of the interfering link General information on the link Interfering transmitter characteristics Position and propagation model information between victim and interferer Wanted receiver characteristics Choose from a library Distribution of the center frequency

  7. Interfering Link ParametersCDMA system CDMA module Distribution of the center frequency Definition of the CDMA unwanted emission mask Selection of the CDMA module

  8. Start a simulation A. Check consistency B. Select the number of snapshots C. Launch a simulation

  9. Interfering link Interfering transmitter (It) Wanted receiver (Wr) Victim link Results: Simulation status interface Mean and std value of dRSS and IRSS (unw and block) Provides basic information on the simulation status Display the victim and interfering link element for each snapshot Progress bar to track the current task status and the system memory Wanted transmitter (Wt) Victim receiver (Vr)

  10. Results: dRSS and iRSS vectors

  11. Results: Interference calculation Translation: Probability of interference as a function of parameters Compatibility: Probability of interference 17.5 % of probability of interference

  12. CDMA interface Provides general information on the CDMA system System characteristic for Uplink or Downlink ) Position of the elements (i.e. antenna , Cell radius, mobility) Setting up of the propagation model Setting up of the number of CDMA users in the network (i.e. capacity) Position of the reference cell to the network

  13. Thank you - Any Questions?
