    • Broadcast Space-Time Coding 

      Memarzadeh, Mahsa; Sabharwal, Ashutosh; Aazhang, Behnaam (2001-08-20)
      In this paper, we study transmission techniques for broadcast channels with a single transmitter and multiple receivers. The transmitter is assumed to be equipped with multiple antennas. Further, each receiver is interested ...
    • Code Design for Multiple-Antenna Systems 

      Memarzadeh, Mahsa (2001-04-20)
      We propose a systematic method for the design of space-time codes for AWGN slowly and fast Rayleigh fading channels. This can be accomplished by adopting a concatenated space-time code structure, where an orthogonal transmit ...
    • Design of Coded Modulation Schemes for Orthogonal Transmit Diversity 

      Borran, Mohammad Jaber; Memarzadeh, Mahsa; Aazhang, Behnaam (2001-05-20)
      In this paper, we propose a technique to decouple the problems of maximizing spatial diversity gain, temporal diversity gain, and coding gain, involved in the design of space-time codes in Rayleigh fading channels. For ...
    • Design of Coded Modulation Schemes for Orthogonal Transmit Diversity 

      Borran, Mohammad Jaber; Memarzadeh, Mahsa; Aazhang, Behnaam (2001-06-20)
      In this paper, we propose a technique to decouple the problems of spatial and temporal diversity gain maximization involved in the design of space-time codes in fast Rayleigh fading channels by using orthogonal transmit ...
    • Optimal digital communication of analog signals 

      Memarzadeh, Mahsa; Johnson, Don (2005-03-01)
      In this paper, the problem of optimally communicating analog sources using a bandwidth and power limited digital system is considered. We propose and analyze optimal combined source-channel coding schemes that jointly ...
