VERSATILE RADIO RECEIVER ARCHITECTURE |
| 摘要 |
The invention concerns an RF receiver comprising: a down-converting and sampling circuit (104) adapted to: receive an RF input signal (RFIN) having a signal band (BWRF) comprising a plurality of sub-bands (BWIF), each sub-band comprising a plurality (2K) of channels separated by frequency channel spaces (ΔfCH); and perform frequency transposition and sampling to generate a discrete time signal in which a selected one of the plurality of sub-bands is brought from an initial frequency band to a lower frequency band (IF20±KΔfCH); and a discrete time filter (108) having a variable pass band, the central frequency (f0) of the discrete time filter being controllable to select any one of the plurality (2K) of channels of the selected sub-band. |

1. An RF receiver comprising:
a down-converting and sampling circuit adapted to:
receive an RF input signal having a signal band comprising a plurality of sub-bands, each sub-band comprising a plurality of channels separated by frequency channel spaces;perform frequency transposition and sampling to generate a discrete time signal in which a selected one of the plurality of sub-bands is brought from an initial frequency band to a lower frequency band; and a discrete time filter having a variable pass band, the central frequency of the discrete time filter being controllable to select any one of the plurality of channels of the selected sub-band. |
