 The  Wireless  Revolution:  A  Signal  Processing  Perspective 
 (A  tutorial  on  Statistical  Signal  Processing  in  Wireless 
 Multiple-  Access  Communications) 


 The  FCC’s  Office  of  Engineering  and  Technology  is  sponsoring  a  tutorial  by  Dr.  Vincent  Poor, 
 Professor  of  Electrical  Engineering  at  Princeton  University.  The  presentation  will  begin  at  1:  30 
 p.  m.  on  Tuesday,  May  29  in  the  Commission  Meeting  Room  (TWC-  305),  445  12  th  Street,  S.  W., 
 Washington,  D.  C.  and  will  last  approximately  two  hours. 


 The  purpose  of  the  presentation  is  to  increase  understanding  of  statistical  signal  processing, 
 primarily  as  applied  to  problems  in  wireless  multiple-  access  communications.  Research  in  this  area 
 has  resulted  in  the  development  of  novel  signal  reception  techniques  for  emerging  wireless 
 communication  systems,  such  as  the  wideband  code-  division  multiple-  access  (W-  CDMA)  systems 
 currently  being  developed  for  voice  and  data  (multimedia)  applications.  A  principal  challenge  in 
 the  development  of  such  systems  stems  from  the  physical  properties  of  the  communication 
 channel,  which  can  include  signal  dispersion,  fading,  impulsive  noise,  cochannel/  multiple-  access 
 interference,  and  narrowband  interference,  as  well  as  other  phenomena  such  as  spatial  or  path 
 diversity  in  the  form  of  multipath  or  multiple  antennas  at  the  transmitter  or  receiver. 


 Other  challenges  in  this  area  include  the  dynamism  that  can  arise  in  such  channels  due  to  mobility 
 and  to  the  use  of  random  channel  access  protocols,  the  need  for  portability  and  increasing 
 demands  for  higher  data  rates  and  larger  user  populations.  These  challenges  give  rise  to  the  need 
 for  new  signal-  processing  algorithms.  The  results  of  recent  research  into  these  matters  can  be 
 found  at  http://  www.  ee.  princeton.  edu/~  steph/  report97.html. 


 Members  of  the  public  may  attend  the  presentation,  and  every  effort  will  be  made  to 
 accommodate  as  many  people  as  possible.  Admittance,  however,  will  be  limited  to  the  seating 
 available  in  the  Commission  meeting  room.  Please  allow  sufficient  time  for  clearance  through 
 Commission  security  before  the  presentation  begins.  For  additional  information,  contact  Kent 
 Nilsson  at  202-  418-  0845  (e-  mail:  knilsson@  fcc.  gov).
