Abstract: In one aspect, an apparatus comprises: a radio frequency (RF) front end circuit to receive and process an RF signal comprising a packet, the RF front end circuit to output a digital signal comprising the packet; and a baseband circuit coupled to the RF front end circuit. The baseband circuit may comprise: a demodulator to receive the digital signal comprising a plurality of extended and modulated symbols and to: perform a plurality of operations on at least some of a first block of the plurality of extended and modulated symbols according to a reverse recipe of operations to obtain a processed first block of the plurality of extended and modulated symbols; aggregate the processed first block of the plurality of extended and modulated symbols into an aggregated symbol; and demodulate the aggregated symbol to obtain at least one soft value.

Abstract: In one embodiment, an apparatus includes a circuit to: modulate a symbol with a sequence; extend the modulated symbol to obtain a plurality of modulated symbols; and perform, on the plurality of modulated symbols, a plurality of operations according to a Recipe of operations, to obtain extended and modulated symbols. The apparatus may further include a radio frequency (RF) front end circuit coupled to the circuit to process and transmit the extended and modulated symbols.
