SYMBOL CONSTELLATION DESIGN

摘要

In embodiments, apparatuses, methods, and storage media may be described for removing, from a frequency domain (FD) portion of a signal, a guard interval portion. One or more data symbols of the resultant unconstrained FD portion of the signal may then be constrained according to one or more tolerance parameters or thresholds. Other embodiments may be described and/or claimed.

1. An electronic device comprising:
guard interval circuitry to: remove, from a first frequency domain (FD) portion of a first orthogonal frequency division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) transmit signal in a radio frame, an FD guard interval portion related to a guard interval of the radio frame; identify, after the removal of the FD guard interval portion, that a data symbol of a data symbol constellation related to the first OFDM or OFDMA signal is at a current position outside of a tolerance related to the data symbol constellation; alter, based on the identification, the data symbol to a new position that is inside of the tolerance to generate a second FD portion; and generate a second OFDMA or OFDMA transmit signal in the radio frame based on the guard interval and the second FD portion; and transmit circuitry to transmit the second OFDM or OFDMA transmit signal in the radio frame.
