An Amateur 900 MHz Spread-Spectrum Radio Design
نویسنده
چکیده
System design principles and high-level design details are described for a new spreadspectrum radio design for the 900 MHz. Amateur band. The radio is designed to provide a 10-base-T interface as the data port, and is designed to provide transport of IP-based data. It is planned to provide both stand-alone and fully-networked hub configurations. The design is based on Frequency-Hopped Spread Spectrum (FHSS) spreading. Use of Forward Error Correction (FEC) and QPSK modulation should provide significant system gain performance compared to other FHSS FSK designs. The radio is currently in the printed-circuit board layout stage.

Extracting Stable Clock Signals From AM Broadcast Carriers for AmateurS Spread-Spectrum Applications
To recover data from spread-spectrum transmissions, it is necessary to reintroduce, at the receiver end, locally generated signals locked in frequency and phase to the clock used in the original transmissions. At carrier frequencies of up to 50 MHz, the extraction of clock pulses from direct-sequence (DS) spreadspectrum transmissions can be achieved fairly easily, using readily available ICs.' ...

This paper presents the measured propagation characteristics like a path loss, delay spread and angular spread for urban environments in Jeju at 781 MHz. Measurements were made with a wide band MIMO channel sounder using a pseudo noise (PN) mode, 50 Mcps, 20 ns resolution and 40.96 μs maximum delay. Base station (BS) antenna height of 5 m was tested with a mobile station (MS) antenna height of ...
متن کاملSystematic Design of High-Performance Smart Card with HF/UHF Dual-Band RFID Tag
Recently, there have been widely conducted researches on dual-band radio frequency identification (RFID) tag based on 13.56 MHz (HF) and 900 MHz (UHF). Most dual-band RFID tag has been implemented so that each antenna is separated in a different inlay sheet respectively, which makes the resulting smart card impractically thick, and the typical drawback of dual-band RFID tags incorporated in one...
