1. An apparatus for wireless communication comprising: at least one processor;
a memory element, in which the memory element contains instructions executable by the at least one processor;
wherein the at least one processor is configured to:
encode data bits to be transmitted over a multiple resource unit (MRU) in a wireless local area network (WLAN);
create a group of the encoded data bits for each spatial stream based on a predetermined criterion;
parse the encoded bits in the group based on a proportional ratio associated with the MRU;
modulate the parsed encoded data bits to generate modulated encoded data symbols;
map the modulated encoded data symbols to data subcarriers to generate encoded data subcarriers, the data subcarriers being associated with respective resource units (RUs) of the MRU;
duplicate the encoded data subcarriers within the respective RUs without performing dual carrier modulation (DCM) over the encoded data subcarriers;
shuffle the duplicate encoded data subcarriers across the respective RUs of the MRU;
transmit the encoded data subcarriers and the duplicate encoded data subcarriers over the MRU in the WLAN; and
wherein the predetermined criterion operates to:
determine a number of data subcarriers NSD associated with the MRU, and
determine a number of data subcarriers NSD,DUP by dividing the number of data subcarriers NSD by a number of times the encoded data subcarriers is to be duplicated within the respective RU.
