MULTI-CARRIER SIGNAL PROCESSOR |
摘要 |
PROBLEM TO BE SOLVED: To reduce the influence of frequency characteristics caused by an analog signal process. SOLUTION: In a multi-carrier signal processor, a compensation process is applied to a generated multi-carrier signal based on a filter coefficient set for compensating frequency characteristics of a transmission unit 14 (analog circuit element).Preferably, a temperature measuring unit 248 for measuring a temperature of the analog circuit element is additionally provided, and an FIR filter 120 carries out a compensating process based on a filter coefficient according to the temperature of the analog circuit element and reduces the influence of temperature dependency of the analog circuit element.
