Systems, devices, and methods for training sequence transmission and reception
A training sequence helps optimize SNR degradation in a wireless communication. Various sets of training sequences may be stored in a repository, and transmitters and receivers encoded with such sequences transmit at least one of the sequences between them as part of the wireless transmission of data.
