Low-power dynamic MIMO detection for a 4×4 MIMO-OFDM receiver
This paper describes low-power dynamic multiple-input and multiple-output (MIMO) detection for a 4×4 MIMO-orthogonal frequency-division multiplexing (MIMO-OFDM) receiver. MIMO-OFDM systems achieve high-speed and large capacity communications. However, they impose high computational cost in MIMO detection when separating spatially multiplexed signals and they consume vast amounts of power. We pr...
متن کاملReceiver implementation for a MIMO OFDM system
Abslra+ln this paper, we present preamble and receiver design for a Q transmit L receive multi input multi output OFDM system. Tasks performed by the receiver are synchronization in time and frequency domains, followed by channel estimation and noise variance estimation. An algorithm is developed such that only Q OFDM symbols of a generalid length are required to perform functions of the preamb...
متن کاملAn Improved Detection Technique For Receiver Oriented MIMO-OFDM Systems
In rich scattering environments, layered Space Time architectures like the BLAST (Bell Labs Layered Space Time) system may exploit the capacity advantage of multiple antenna systems. In case of a broadband wireless transmission, the channel undergoes frequency selective fading which necessitates the receiver to have a multi tap equalizer. This can be avoided by employing an OFDM (Orthogonal Fre...
متن کاملA Low-Power Adaptive MIMO Detector for MIMO-OFDM WLAN Systems
A MIMO-OFDM receiver requests high-speed MIMO detection to separate spatially multiplexed signals on real-time processing, which causes large power dissipation due to its high throughput performance. We present an adaptive MIMO detector which adaptively changes the computational speed of MIMO detection by estimating Doppler shifts correlated with fading channel variations. The adaptive detector...
متن کاملLow Power Efficient MIMO-OFDM Design for 802.11n WLAN System
In modern world of communication systems, various new methods have developed to replace the previous conventional techniques that provide data communication with high speed. As wireless communication guidelines were developed it became necessary to develop new techniques like Orthogonal Frequency Division Multiplexing (OFDM) for data security and reliability while data transmission. Idea behind...
