On time-varying cyclic delay diversity
: Cyclic Delay Diversity (CDD) was introduced in 2001 to obtain spatial diversity in an Orthogonal Division Multiplexing (OFDM) based transmission system. In contrast to Space-Time...

Progressive Image Transmission over OFDM Systems using Multiple Antennas
A Joint source-channel coding (JSCC) scheme for SPIHT coded image transmission over OFDM systems with spatial diversity is proposed where no feedback channel is available. By usin...
