Heading: A transceiver for transmitting a first stream

Text: of data symbols, the transceiver comprising: a converter for converting the first stream of data symbols into plural sets of N data sym- bols each; first computing means for operating on the plu- ral sets of N data symbols to produce modu- lated data symbols corresponding to an invertible randomized spreading of the first stream of data symbols; and means to combine the modulated data symbols for transmission. The claimed transceiver includes a “converter” for converting a stream of data symbols into multiple sets of data symbols, where each set includes N symbols. Second, the transceiver includes a “computing means” for operating on the sets to produce “modulated data symbols corre- 6 WI-LAN, INC. v. APPLE INC. sponding to an invertible randomized spreading” of the original data symbols. Finally, the transceiver includes a “means to combine the modulated data symbols for transmission.” Asserted claim 10, which depends on claim 1, adds means for receiving and decoding the data symbols.
