Abstract
An example system for encoding OFDM data may comprise a processor and a transmitter. The processor may be configured to encode OFDM symbols into a first sigma-delta (ΣΔ) modulated bitstream, such that spectral content of the first sigma-delta (ΣΔ) modulated bitstream contains tones at subcarrier frequencies corresponding to the encoded symbols. The transmitter may be configured to transmit the sigma-delta (ΣΔ) modulated bitstream to a receiver.

A system for encoding OFDM data, the system comprising:
- a processor configured to encode OFDM symbols into a first sigma-delta (ΣΔ) modulated bitstream, such that spectral content of the first sigma-delta (ΣΔ) modulated bitstream contains tones at subcarrier frequencies corresponding to the encoded symbols;
- and
- a transmitter configured to transmit the sigma-delta (ΣΔ) modulated bitstream to a receiver.
A method, comprising:
- encoding OFDM symbols, by a processor, into a first sigma-delta (ΣΔ) modulated bitstream, such that spectral content of the first sigma-delta (ΣΔ) modulated bitstream contains tones at subcarrier frequencies corresponding to the encoded symbols;
- and
- transmitting, by a transmitter, the sigma-delta (ΣΔ) modulated bitstream to a receiver.
