【Abstract】 To solve the problem about the coverage of SCDMA system in rural area, using Tower Top Amplifier(TTA) is a perfect solution. The analysis result indicates that employ of TTA can extend the coverage, decrease RF channel noise factor, and reduce the cost of network construction. TTA design puzzles in SCDMA system are analyzed and the solution is given.更多还原
