| Abstract: |
| According to the requirement of time domain and frequency doma
in analysis of signals for mobile base stations, the portable signal monitoring
equipment
is proposed in this paper, which applies a minimum monitoring system based on TM
S320F28234 and a RS-232/USB communication conversion module. Several key technol
ogies are discussed, including real FFT algorithm, serial communic
ation protocol, design of main program, etc. All these methods ensure that the s
ystem can implement signal acquisition, A/D conversion, spectral analysis, commu
nication between master computer and this equipment, and signal analysis. Theref
ore the equipment can provide the operation status of communication system to ma
ke mobile base station be under normal operation state. |
