Upon completing the design of lattice offline, the messages are modulated to this lattice online and then transmitted to all relays.
The acceleration signal was modulated to an optic signal using pulse width modulation (PWM), and the modulated optic signal was transmitted outside the fMRI room using a light emitting diode (LED) and optic cable.
In order to transmit computer data and other digitized information over a communications channel, an analog carrier wave can be modulated to reflect the binary nature of the digital baseband signal.
The decoded bit vector is then re-coded and re-modulated to regenerate the transmitted symbol vector x → ^ K.
At each k th channel, the estimated symbol vector x ¯ k, D is generated by using each MMSE de-spreading vector w ¯ k from (15) to yield a de-spread signal vector of x ¯ ̂ k T = w ¯ k H R k and an estimated bit stream u ¯ k, D. The decoded bit vector u ¯ k, D is re-coded at the receiver and re-modulated to regenerate the transmit symbol vector x ¯ k, D at the output of the decision device.
Each element, z n, of the transmission vector z → , for n = 1,..., N, is then filtered using a pulse shaping function at regular intervals of chip period T c before being modulated with an up converter to transmit the data at the desired frequency.
In the spinal cord, the incoming signals are then modulated, transmitted to second order neurons by neurotransmitters, and passed to the brain stem via ascending pathways.
This allows the light-wave signal carrier to be modulated at very high frequencies and to transmit a high volume of information traffic.
These encoded sequences are then BPSK (Binary Phase Shift Keying) modulated and transmitted to a common receiver over a Gaussian Multiple-Access Channel. Figure 2 Block diagram of the considered scenario.
It then encodes each measurement along with the node's location tag into a packet, which is digitally modulated and transmitted to the FC in a random access fashion.
