An Overview of Cyclic Delay Diversity and its Applications
Cyclic Delay Diversity (CDD) is a diversity scheme used in OFDM-based telecommunication systems, transforming spatial diversity into frequency diversity and thus avoiding intersymbol interference. CDD was introduced in 2001 and can gain frequency diversity at the receiver without changing the SISO receiver structure. WebOct 1, 2006 · The power potential of radio links is realized when encoding is introduced into DSCS with multistation access. We recall the principles of Cyclic Delay Diversity (CDD) and discuss the properties ... WebCDD (Cyclic Delay Diversity) CDD is a kind of transmit diversity mechanism implemented by applying a different phase delay (cyclic phase delay) for each OFDM subcarrier. It is used in spatial multiplexing to … p99 the kly
