System and method for providing multiple bandwidth support using a frequency shifter

A method for supporting multiple bandwidth, the method comprising:

• generating, by a processor (202) associated with a system (108), one or more samples from one or more subcarriers using an Inverse Fast Fourier Transform (IFFT) technique during a modulation stage and using a Fast Fourier Transform (FFT) technique during a de-modulation stage;
• computing, by the processor (202), one or more phase coefficients associated with the one or more subcarriers;
• and
• augmenting, by the processor (202), the one or more samples with the one or more phase coefficients to generate a time domain frequency shift associated with the one or more samples for transmission/reception to/from a computing device (104) associated with one or more users (102).

A user equipment (UE) (104), comprising:

• one or more processors communicatively coupled to a processor (202) associated with a system (108), wherein the one or more processors are coupled with a memory, and wherein said memory stores instructions which, when executed by the one or more processors, cause the one or more processors to:
• augment one or more modulated samples to generate a time domain frequency shift associated with the one or more modulated samples;
• in response to the time domain frequency shift, compute one or more phase coefficients associated with one or more subcarriers;
• and
• generate one or more samples from the one or more subcarriers using a Fast Fourier Transform (FFT) technique during a de-modulation stage and using an Inverse Fast Fourier Transform (IFFT) technique during a modulation stage.

A non-transitory computer readable medium comprising a processor with executable instructions, causing the processor to:

• generate one or more samples from one or more subcarriers using an Inverse Fast Fourier Transform (IFFT) technique during a modulation stage and using a Fast Fourier Transform (FFT) technique during a de-modulation stage;
• compute one or more phase coefficients associated with the one or more subcarriers;
• and
• augment the one or more samples with the one or more phase coefficients to generate a time domain frequency shift associated with the one or more samples for transmission and reception.
