Abstract: Methods, systems, and devices for transmitter-side processing of preamble and reference signals are described. An exemplary method for wireless communication includes transmitting, by a wireless device, a message comprising modified symbols that are generated by performing a modification on baseline symbols. Another exemplary method for wireless communication includes receiving, by a network node, a message comprising modified symbols that are generated by performing a modification on baseline symbols. In an example, the message may be a random access message that is part of a 2-step random access channel (RACH) process or a contention-based physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) transmission.
