Circuit-Switching Physical Layer Based on Time-Frequency Coding for Multi-Band UWB Wireless Networks

The article describes physical layer (PHY) for high data-rate self-organized wireless networks based on the Ultra Wideband (UWB) technology with frequency band [3.1 - 10.6] GHz. The developed transceiver scheme has wide range adaptation features and cross-layer elements based on convergence of maximum likelihood sequence estimation (MLSE) equalizer and frequency hopping (FH). Circuit switching technology for multiply access and data transmission is one of key-notes of developed PHY architecture.
