A Method for Rate Selection in OFDM Wireless Networks

Project ID: 1736-AP
Available for licensing

Background

Wireless networks depend on accurate selection of physical layer parameters to maximize throughput under reliability constraints (such as packet error rate).

Invention Description

This invention enables a new method for completing rate adaptation in wireless networks. A new method for selecting the physical layer parameters in a OFDM or MIMO-OFDM (multiple-input, multiple-output and orthogonal frequency division multiplexing) wireless network is proposed.

Benefits

Improves reliability of rate adaptation.
Results in less congestion in a network as well as less energy consumed.

Features

Reduces the dimensionality of adaptation by reducing the dimensionality of adaptation.
Metrics are extracted from wireless channel information.
More accurate rate adaptation results in higher data rates and increased reliability of the wireless network.

Market Potential/Applications

Modern wireless networks such as IEEE 802.11a/b/g/n
