发明名称 Cyclic shift delay (CSD) short training field (STF) for orthogonal frequency division multiplexing (OFDM) signaling within multiple user, multiple access, and/or MIMO wireless communicaitons
摘要 Cyclic shift delay (CSD) short training field (STF) for use within multiple user, multiple access, and/or MIMO wireless communications. Appropriately designed CSD STF is applied to communications in wireless communication systems thereby ensuring a minimized power error difference between respective portions of a packet transmitted therein. A first portion of the packet may be a short training field (STF) and a second portion of the packet may be a payload (e.g., a data portion). By applying such appropriately designed CSD STF to a packet, a wireless communication device that receives 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 processing of that signal 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.
