an efficient transmission scheme for high speed wireless systems - Isis Project No 3247
A novel method to reduce interchannel interference in multi-channel wireless communication systems with no additional hardware cost and system complexity.
MARKETING OPPORTUNITY
Wireless communication is a multibillion-dollar market and newer applications are pushing the demand for high-speed and high quality data transfer that requires efficient transmission schemes. Orthogonal Frequency Division Multiplexing (OFDM) is a digital modulation technique, which closely meets these requirements. However, current OFDM systems have performance issues such as weak reception power and low signal-to-noise ratio.THE OXFORD INVENTION
Oxford University inventors have developed a novel signal-processing scheme, which mathematically manipulates the transmitted and received signals to enhance the desired signal power capture and reduce inter-channel interference in conventional OFDM systems (see figure). The proposed scheme can be applied to any OFDM systems used in commercial applications such as digital radios, television broadcasts and wireless local area networks etc.The proposed invention offers several advantages:
- No additional hardware
- Reduced system complexity
- Higher data rates
- Applicable to all single or multiband OFDM systems and wire-line or wireless systems
- Applicable to both wide and ultra wide band systems
