TRELLIS CODED DFTS-OFDM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18517186 titled 'TRELLIS CODED DFTS-OFDM
Simplified Explanation
The abstract describes a method, computer-readable medium, and apparatus for encoding input bits using a Trellis code to generate output symbols, shaping them in the frequency domain, mapping them onto subcarriers, generating a time domain waveform, and transmitting it.
- The apparatus is a transmitter.
- The transmitter encodes input bits using a Trellis code.
- The Trellis code confines amplitude fluctuations between consecutive output symbols.
- The transmitter pulse shapes the output symbols in the frequency domain.
- The transmitter maps the pulse shaped symbols onto subcarriers.
- The transmitter generates a time domain waveform based on the mapped symbols.
- The transmitter transmits the time domain waveform.

Original Abstract Submitted
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a transmitter. The transmitter receives a plurality of input bits. The transmitter encodes the plurality of input bits using a Trellis code to generate a plurality of output symbols. The Trellis code is configured to confine amplitude fluctuations between consecutive output symbols. The transmitter pulse shapes the output symbols in a frequency domain. The transmitter maps the pulse shaped symbols onto a plurality of subcarriers. The transmitter generates a time domain waveform based on the mapped symbols. The transmitter transmits the time domain waveform.
