    Abstract: A molecular data storage system is presented for encoding data-block(s). The system includes one or more populations of molecular sequences, each population encoding a respective one of the data-blocks. Each molecular sequence comprises a data encoding section comprising a sequence of similar predetermined length N of short k-mers, whereby in each population the data encoding sections of all molecular sequences have the similar predetermined length N. The short k-mers serve as data encoding building blocks of the data encoding sections, whereby valid short k-mers serving as data encoding building blocks form a subset of a building-block-set consisting of a number Z of different preselected short k-mers each presenting a unique combination of a number k of bases of a preselected set of bases, characterized in that all the Z types of short k-mers in said building-block-set have a similar predetermined size k≥2 (plurality) of bases. The data encoding sections collectively encode a sequence of encoded alphabet letters S=(π1, π2, . . . , πn . . . , πN−1, πN). Each valid encoded alphabet letter πn at location n of the sequence S of alphabet letters is characterized by occurrence of a predetermined plurality of different types of short k-mers of the building-block-set in a corresponding location n along the data encoding sections of the plurality of molecular sequences of said population.

    Abstract: An electro-optic system, the electro-optic system that may include an input port that is configured to receive a bandpass signal that conveys information; wherein the bandpass signal is a radio frequency (RF) signal; an optical carrier source that is configured to generate an optical carrier signal having an optical carrier frequency; at least one electrical bias circuit that is configured to generate at least one electrical bias signal; an electro-optic modulation circuit that is linear at the optical field; a manipulator that is configured to (a) receive the at least one electrical bias signal and the bandpass signal, (b) generate, based on the at least one electrical bias signal and the bandpass signal, at least one modulating signal; wherein the electro-optic modulation circuit is configured to modulate the optical carrier by the at least one modulating signal to provide an output optical signal that comprises at least one optical pilot tone and at least one optical sideband that conveys the information.

    Abstract: An orthogonal frequency division multiplexing (OFDM) transmitter that includes an encoder, an interleaver, a symbol processor; and a transmission module; wherein the encoder is configured to encode a superframe to provide an encoded superframe; wherein the encoded superframe comprises a sequence of encoded frames; wherein the interleaver is configured to allocate multiple frequency sub-bands to each encoded frame of the encoded superframe by assigning adjacent frequency sub-bands to successive symbols of each encoded frame; wherein the symbol processor is configured to generate, for each encoded frame and according to the assignment of the multiple frequency sub-bands, an intermediate set of symbols; and wherein the transmission module is configured to transmit simultaneously, for each encoded frame, OFDM symbols that represents the intermediate set of symbols.
