Chip level LMMSE Equalization for Downlink MIMO CDMA in fast fading environments
In this paper, we consider linear MMSE equalization for wireless downlink transmission with multiple transmit and receive antennas in fast fading environment. We propose a new algorithm based on conjugate-gradient algorithm ...
On Turbo-Schedules for LDPC Decoding
The convergence rate of LDPC decoding is comparatively slower than turbo code decoding: 25 LDPC iterations versus 8-10 iterations for turbo codes. Recently, Mansour proposed a â turbo-scheduleâ to improve the convergence rate ...
Channel equalization algorithms for MIMO downlink and ASIP architectures
Processors for mobile handsets in 3G cellular systems require: high speed, flexibility and low power dissipation. While computationally efficient, ASIC processors are often not flexible enough to support necessary variations ...
White Paper on IEEE 802.11b Mobile Channel Modeling
Researchers from Rice Universityâ s Center for Multimedia Communications (CMC) recently conducted experiments with the goal of understanding and quantifying the effects of various channel effects on an 802.11b link. In ...
Channel Equalization Algorithms for MIMO Downlink and ASIP Architectures
Processors for mobile handsets in 3G cellular systems require: high speed, flexibility and low power dissipation. While computationally efficient, ASIC processors are often not flexible enough to support necessary ...
ASIP Architecture for Future Wireless Systems: Flexibility and Customization
Efficiency and flexibility are crucial features of the processors in the next generation of wireless cellular systems. Processors need to be efficient in order to satisfy real-time requirements for very demanding algorithms ...
802.11b Operating in a Mobile Channel: Performance and Challenges
In the past, the worlds of wireless voice and data transmission have been largely disjoint. Voice traffic has been carried over circuit-switched cellular links, and data has been largely restricted to packet-switched ...
Architecture and Algorithm for a Stochastic Soft-output MIMO Detector
In this paper, we propose a novel architecture for a soft-output stochastic detector in multiple-input, multiple-output (MIMO) systems. The stochastic properties of this detector are studied and derived in this work, ...
