In this letter, according to the analysis of existing transmission matrices of quasi-orthogonal space-time block codes (STBC), we generalize some of t...

OFDM systems typically use coding and interleaving across subchannels to exploit frequency diversity on frequency-selective channels. This letter pres...

Wide-band radio channel measurements at 5.2 GHz with four transmit and four receive antennas at variable element spacing are reported, aiming to evalu...

It has been predicted theoretically that for some environments, the capacity of wireless multiple-input multiple-output systems can become very low ev...

Multiuser diversity has attracted significant attention recently. In this letter, we propose a greedy algorithm based on QR decomposition of the chann...
