Apparatus, system and method of an orthogonal frequency-division multiplexing (ofdm) transmission over a wide bandwidth

An apparatus of Orthogonal Frequency-Division Multiplexing (OFDM) transmission, the apparatus comprising:

• an encoder to encode scrambled data bits of a Physical layer (PHY) Protocol Data Unit (PPDU) into encoded data bits, the PPDU to be transmitted in an OFDM transmission over a 320 Megahertz (MHz) aggregated bandwidth comprising first and second contiguous 160 MHz channels in a 6 Gigahertz (GHz) frequency band;
• a stream parser to parse the encoded data bits of the PPDU into a plurality of data streams;
• a plurality of 160 MHz segment parsers to parse the plurality of data streams into first and second pluralities of 80 MHz frequency blocks, a 160 MHz segment parser of the plurality of segment parsers to parse a respective data stream of the plurality of data streams into a first 80 MHz frequency block of the first plurality of 80 MHz frequency blocks and into a second 80 MHz frequency block of the second plurality of 80 Mhz frequency blocks;
• and
• a first baseband processor to process the first plurality of 80 MHz frequency blocks;
• and
• a second baseband processor to process the second plurality of 80 MHz frequency blocks.
