---+ Product Backlog

---++ Maybe

• GUI: Include eigenvalues
• Program a GUI in Matlab to plot capacity results
• Documentation Calibration
• Matlab Toolbox: Align impulse responses for PDP calculation using the autocorrelation function

---++ Todo

• Implement a TX power control for the MRs (CH sends TX power and target RSSI in CHBCH, MR computes path loss (TX power - RX RSSI), MR adjusts TX power = target RSSI + path loss)
• Include calibrated noise level in measurements & FIFO

---++ In Progress

---++ Done

• Simulation mode
• Realtime module for PHY and MAC
• GUI
• Matlab import filter
• Measurement dump to disk
• EMOS transmitter code (set recording flag on/off)
• Platoon: Running
• Demo for SFR on Thursday
• Multiuser Import Filter
• Check calibration of cards
• Debug Automatic Gain Control
• Evaluate measurements from 31.10.07
• Check Tx antenna no. 4
• Evaluate measurements of 5.11.07
• GUI: Redesign recording functionality
• Matlab Import Filter: Fix out of memory problem (read data in two passes, firstly only the metadata + compute normalization factor, secondly only the needed frames)
• Documentation Matlab scripts
• Second Measurement Campaign
• Matlab MU Import filter: Fixed problem with alignment of first frame
• Calculate Rx antenna correlation coefficient
• MU Capacity calculation
  • Scenario 0: 4 users, 4x2, 2 streams each: Time-sharing single link MIMO (we assume no scheduling, that means we calculate the SU capacity for every user and take the mean of it)
  • Scenario 1: 4 users, 4x1, 1 stream each: Fix one antenna at Rx + ZF Precoder
  • Scenario 2: 4 users, 4x2, 1 stream each: Antenna selection at Rx + ZF Precoder
  • Scenario 3: 2 users, 4x1, 1 stream each: Fixed Antenna + ZF
  • Scenario 4: 2 users, 4x2, 1 stream each: Antenna selection at Rx+ ZF
  • Scenario 5: 2 users, 4x2, 2 streams each: Block Diagonalization
  • The antenna selection procedure shall be based on groups of 6 subcarriers or the whole band
• Other Performance Metrics
  • Orthogonality of users: 1/trace(H H^H)^-1
• MU capacity calculation for iid channels (Marios)
• Debugging block diagonalization
• Evaluation of 2nd measurement campaign
• Matlab Report generation
• Check calibration of card 7
• Presentation SFR
  • Describe Normalization
  • Describe capacity calculations, antenna selection, etc. in more detail
  • Add conclusions
  • Capacity plots: when comparing to AS, keep one of the non-AS curves
  • Check capacity of iid channel with AS
  • Check capacity of correlated channels (Copy channel of Rx antenna --> high correlation)
  • Draw Antenna Sector on Map
  • Include a slide with system parameters and measurement description
  • Annotate coverage map
  • SUTS capcity --> do not average over users
  • Define A and Q
  • Update conclusions
  • Update capacity plots
    • SU-MIMO TDMA vs 2U MU-MIMO ZF and 2U MU-MIMO MMSE (measured only)
    • 2U MU-MIMO ZF and 2U MU-MIMO MMSE (measured + iid)
    • SU-MIMO TDMA vs 4U MU-MIMO ZF and 4U MU-MIMO MMSE (measured only)
    • AS as is w/o iid plots
  • Update Legend in RSSI plot
• Order batteries for laptops
• Kangoo: replace/charge battery
• Plot eigenvalues of channel matrix over time, eigenvalue distribution
• Calculate the full correlation matrix, averaging over all frequencies
• CDF in logarithmic scale
• Check FER over SNR
• Calculate capacity for single user open loop 4x2 MIMO with MMSE receiver
• Plan indoor and another outdoor campaign
• SFR Report/presentation
• SPAWC paper
• COST paper/presentation
• Check processing gain
• Get EMOS to run with two synchronized BS
• Make EMOS two-directional
• Write frequency offset estimate to FIFO
• Find bug that makes EMOS crash when module is removed -> it was writing a big structure to fifo
• Put frame no from CH1 in MRBCH
• Fill PHY_measurements in CH with meaningful data (do normal channel estimation in 1st symbol of SCH0 and SCH1)
