Claim Text:
1. An apparatus for wireless communications, comprising: one or more encoders configured to encode data according orthogonal frequency division multiplexing to obtain encoded bits; a stream parser configured to partition the encoded bits into a plurality of partitions of bits associated with a plurality of spatial streams; a segment parser configured to segment each of the partitions of bits across two or four 40 megahertz (MHz) bandwidth segments; a first circuit configured to down-clock signal samples associated with the segmented encoded bits by a factor; a second circuit configured to select one or more inter-frame timing parameters utilized in transmitting the down-clocked signal samples, wherein the one or more inter-frame timing parameters comprise at least one of a Clear Channel Assessment (CCA)-Time, a RxTx-Turnaround-Time, an Air-Propagation-Time, a Medium Access Control (MAC)-Processing-Delay, a Slot-Time, a Short Inter-Frame Space (SIFS) time, or a Distributed Inter-Frame Space (DIFS); and a transmitter configured to transmit the down-clocked signal samples utilizing a plurality of waveforms in accordance with a communication standard configured for utilizing television (TV) whitespace.
