Abstract: An orthogonal frequency division multiplexing (OFDM) transmitter maps a digital level into I and Q components. The transmitter uses every other digital level as an I or Q component or divides the MSBs and LSBs of a digital level into the I and Q components. An analog OFDM transmitter uses a pair of input analog levels as the I and Q components. An inverse FFT outputs a complex value and OFDM symbols are transmitted. An inverse FFT may also output a real value using complex conjugates. An optional encoder encodes digital or analog samples into L levels using N orthogonal codes before input into the OFDM transmitter. OFDM receivers receive the OFDM signal and output digital or analog samples. Video signals are input into a distributor that distributes analog or digital samples into vectors, each vector input into an OFDM transmitter that transmits to a corresponding receiver.

The frequencies of the LO signals may be symmetrically spaced around a desired frequency (fLO). Each N-path filter may be coupled to a source of the common-gate device of the coupled cascode amplifier. The LO signals may be generated by a digital-to-time converter (DTC)-based frequency synthesizer. The frequencies of the LO signals supplied to the N-path filters may be adjusted to tune the bandwidth of the bandpass LNA.
