Modulation-adaptive cooperation in Rayleigh fading channels with imperfect CSI
Adaptive modulation can improve the throughput of cooperative communications, which has been shown in previous research. So far the adaptive modulation is applied with respect to ...

Uplink Capacity of Single-Carrier Frequency-Interleaved Spread Spectrum Multiple Access
—A single-carrier frequency-interleaved spread spectrum multiple access (SC-FI-SSMA), which we recently proposed, uses frequency-domain interleaving and MMSE-FDE to remove the up...

Diversity Multiplexing Tradeoff in Multiple Antenna Multiple Access Channels with Partial CSIT
Abstract— We derive a lower bound on the diversitymultiplexing tradeoff for multiple antenna multiple access channels using temporal power control (PC). We quantify the substanti...

Enabling on-chip diversity through architectural communication design
- In this paper, we explore a new concept, called on-chip diversity, and introduce a design methodology for such emerging systems. Simply speaking, on-chip diversity means mixing d...
