Frequency-hopping Spread Spectrum
Frequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly changing the carrier frequency among many frequencies occupying a large spectral band. The changes are controlled by a code known to both transmitter and receiver (radio), receiver. FHSS is used to avoid interference, to prevent eavesdropping, and to enable code-division multiple access (CDMA) communications. The frequency band is divided into smaller sub-bands. Signals rapidly change ("hop") their carrier frequencies among the center frequencies of these sub-bands in a determined order. Interference at a specific frequency will affect the signal only during a short interval. FHSS offers four main advantages over a fixed-frequency transmission: # FHSS signals are highly resistant to narrowband Interference (communication), interference because the signal hops to a different frequency band. # Signals are difficult to intercept if the frequency-hopping pattern is not known. # Jamming is ...

Fuhua Secondary School
Jurong West is a planning area and residential town located in the West Region of Singapore. Jurong West shares boundaries with Tengah in the north, Jurong East in the east, Boon Lay and Pioneer in the south, and Western Water Catchment in the west. Originally a forested area, Jurong West is undergoing rapid development under the ambition of the Housing and Development Board (HDB) to transform it into a fully mature housing estate. History Jurong West originated from the area once called Peng Kang, named after the gambier plantations along Sungei Jurong. By the mid-20th century, the area was home to several brickworks, palm oil plantations and nurseries. At that time, the only public housing estates in Jurong West were Boon Lay and Taman Jurong. Jurong West was largely left alone until 1984, when the HDB began conceptualisation for a new town in Jurong West. Jurong West was carved into nine subzones that would house a total of 94,000 public and private housing units in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
