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 ...

Performance of STBC MC-CDMA systems over outdoor realistic MIMO channels
This paper deals with orthogonal Space-Time Block Coded MC-CDMA systems, in outdoor realistic downlink scenarios with up to two transmit and receive antennas. Assuming no channel s...

Transmit selection diversity with maximal-ratio combining for multicarrier DS-CDMA wireless networks over Nakagami-m fading chan
Abstract--We propose the scheme to integrate transmit selection diversity/maximal-ratio combining (TSD/MRC) with multicarrier (MC) direct-sequence code-division multiple access (DS...

Multi-layer broadcasting hybrid-ARQ strategies for block fading channels
Conventional hybrid automatic retransmission request (HARQ) is usually used to maximize throughput. However, high throughput is achieved at the expense of high latency. We study a...

Differential diversity-embedding space-time block coding for 2 and 4 transmit antennas
Diversity-Embedding Space-Time Block Coding (DE-STBC), introduced in [1], enables Unequal Error Protection (UEP) using multiple transmit antennas. Even though these codes do not re...
