• Rateless coding
• Raptor code
• channel capacity

It is known that the Raptor code can be constructed to achieve a rate close to the capacity of the binary-input AWGN (BIAWGN) channel with a fixed signal-to-noise ratio (SNR). In this letter, we propose a constructive approach of designing the Raptor code over the BIAWGN channel such that the achieved rates are close to the associated capacities for wide SNR ranges.
