An Efficient Differential MIMO-OFDM Scheme with Coordinate Interleaving
EURASIP Journal on Wireless Communications and Networking, 2007 We propose a concatenated trellis code (TC) and coordinate interleaved differential space-time block code (STBC) for OFDM. The coordinate interleaver, provides signal space diversity and improves the codeword error rate (CER) performance of the system in

Blind Channel Estimation for Space-Time Coded WCDMA
EURASIP Journal on Wireless Communications and Networking, 2004 A new blind channel estimation technique is proposed for space-time coded wideband CDMA systems using aperiodic and possibly multirate spreading codes. Using a decorrelating front end, the received signal is projected onto a subspace from which channel

Differential detection scheme for distributed MIMO systems in fast fading channel
Tongxin xuebao, 2012 In the fast fading distributed MIMO system,it is difficult to keep the channel fading coefficient unchanged in adjacent space-time blocks due to the rapid changed state information,which leads to the traditional distributed MIMO differential detection ...
