RF LINK SIMULATOR FOR CDMA |
摘要 |
a distributing means 202 for inputting the signal corresponding to the input frequency which is generated from a first signal generating means 201; a first mixing means 203 for outputting and mixing the output of the distributing means 202 and a reference data; a first filtering means 204 for outputting and removing the spurious signal by inputting the output of the first mixing means 203; a first amplifying means 205 for outputting and amplifying the output from the first filtering means 204; a sending means 206 for sending the output amplified by the first amplifying means 205; a first fading means 207 for fading the output from the sending means 206 to a receivable level at a receiving side; a second mixing means 208 for adjusting the frequency by using a second signal generating means 209 in order to adjust the signal passed through the first fading means 207 to the receivable frequency of a receiving side; a second fading means 210 for outputting and adding an electric wave environment to the signal passed through the second mixing means 208; a receiving means 211; a third mixing means 212; a second filtering means 213; a second amplifying means 214; and a data generating means and data detecting means 215.
