Adaptive Modulation and Power Allocation Technique for LDPC-Coded MIMO-OFDMA Cellular Systems
An adaptive transmission scheme, in which the work in [3] is extended to multiuser environment, is proposed for LDPC-coded MIMO-OFDMA cellular systems that employ FDD by considering active user selection and sub-channel power allocation. The performance of the proposed scheme is obtained from simulation and compared with that of the conventional scheme using mean SNR only. It is shown that the ...
متن کاملPower Allocation Scheme for Coded MIMO Multi-Carrier Systems
Orthogonal Frequency Division Multiplexing (OFDM) is a popular method for high data rate wireless transmission. Combining OFDM with antenna arrays at the transmitter and receiver enhances the capacity gain. This paper proposes a novel transmit power allocation for Coded MultiInput Multi-Output Multi-Carrier Modulation (MIMO-MCM). This technique consists of adapting the power allocation in the s...
متن کاملPerformance Evaluation of Linear Detectors for LDPC-Coded MIMO Systems
This paper investigates the performance of linear detectors namely the Minimum Mean-Squared-Error (MMSE) and the Zero-Forcing (ZF) suboptimal detection schemes for Multiple Input Multiple Output (MIMO) signals over an additive white Gaussian noise (AWGN) channel. Unlike the ZF detector which suffers from noise enhancement, it will be shown that the MMSE detector which takes noise into account p...
متن کاملLDPC Coded Turbo Equalization for MIMO System
—In this paper, MIMO (Multiple-Input-Multiple Output) system based on turbo equalization techniques which LDPC (Low Density Parity Check) codes were outer code and STTC (Space Time Trellis Code) were employed as an inner code are studied. LDPC decoder and STTC decoder are connected through the interleaving and de-interleaving that updates each other's information repeatedly. On the receiver si...
متن کاملPower Allocation Strategies for MIMO Radar Waveform Design
The role of waveform design is central to effective radar resource management for state-of-the art radar systems. The waveform shape employed by any radar system has always been a key factor in determining the performance and application. The design of radar waveform to minimize mean square error (MSE) in estimating the target impulse response is based on power allocation using waterfilling. ...
