摘要: When a wireless communication device is receiving, a baseband circuit generates frequency domain LTE and WCDMA signals using a Fourier transform. The frequency domain WCDMA signal is then filtered with an RRC filter and converted back to the time domain using an inverse discrete Fourier transform. During transmission, the baseband circuit uses a Fourier transform to convert a time domain WCDMA signal to a frequency domain WCDMA signal. The frequency domain WCDMA signal is then filtered with an RRC filter and combined with a frequency domain LTE signal using an inverse Fourier Transform.
