 Tutorial  on  “Capacity  Enhancement  Methods  for  Wireless  Networks” 
 On  February  20,  2004,  the  FCC’s  Office  of  Engineering  and  Technology  will  provide  a  tutorial  on  “Capacity  Enhancement  Methods  for  Wireless  Networks:  Complementary 
 Beamforming,  Space-  Time  Coding  and  Space-  Time  Collaborative  Communications”  from  10:  00  to  12:  00  noon  in  the  Commission  Meeting  Room  (TW-  C305),  445  12  th  Street,  S.  W., 
 Washington,  D.  C. 
 The  speaker,  Dr.  Vahid  Tarokh  is  currently  Gordon-  McKay  professor  of  electrical  engineering  at  the  Harvard  University  and  a  Vinton  Hayes  senior  research  fellow.  He  is  responsible  for  a 
 number  of  inventions,  most  notably  his  pioneering  invention  of  Space-  Time  Coding  (jointly  with  Seshadri  and  Calderbank)  and  Complementary  Beamforming  Techniques  (jointly  with 
 Alamouti  and  Choi).  Dr.  Tarokh  has  been  ranked  in  the  list  of  Top  10  Most  Cited  Authors  in  Computer  Science  by  the  ISI  Web  of  Science.  He  has  also  received  a  number  of  awards 
 including  Gold  Medal  of  the  Governor  General  of  Canada,  1995  IEEE  Information  Theory  Society  Prize  Paper  Award  1999,  the  National  Science  Foundation’s  The  Alan  T.  Waterman 
 Award  2001. 
 In  his  talk  he  will  discuss  capacity  enhancements  methods  based  on  antenna  arrays  for  wireless  networks.  Space-  time  coding  methods  that  are  not  in  general  backward  compatible  with  existing 
 WLAN  standards  will  be  reviewed.  Motivated  by  the  issues  of  backward  compatibility,  he  will  then  discuss  beamforming  and  complementary  beamforming  for  carrier  sensing  wireless 
 networks,  followed  by  some  recent  results  on  collaborative  space-  time  communications. 
 Those  who  wish  to  attend  this  tutorial  will  be  seated  on  a  first-  come  first-  serve  basis.  Reservations  are  neither  accepted  nor  required.
