Legacy cyclic shift delay (CSD) for use within multiple user, multiple access, and/or MIMO wireless communications. Appropriately designed CSD is applied to communications in wireless communication systems thereby ensuring a minimized power error difference between respective portions of a packet transmitted therein. Such respective portions of the packet may be portions of the packet's preamble. For example, the first and second portions may be a legacy short training field (L-STF) and a very high throughput short training field (VHT-STF). By applying such appropriately designed CSD to a packet, a wireless communication device receiving a signal corresponding to that packet need not perform extra or very significant backoff (e.g., with respect to a signal subsequent to automatic gain control (AGC) processing) thereby simplifying signal processing and potentially also reducing a total number of effective analog to digital converter (ADC) bits needed to represent a digitally sampled version of that signal.
