The convolution between b k and h k causes each nonzero transmitted chip to interfere with the samples within the same PPM symbol (intrasymbol interference) and also within adjoining PPM symbols (intersymbol interference).
After TPC commands generation, the transmit chip power is adjusted (see Figure 3) in response to these commands: if TPC cmd = "0", the transmit power is reduced by δ dB which is the power control step size.
The received signal, associated to the m th transmitted multicode chip is given by y m = H x m + n m, (2.2).
Furthermore, denotes the largest integer smaller than and represents the delay of the transmit chips, and denotes the remainder of the integer division and represents the index of the substream.
With amplitude of the miniature wireless chip transmitting a continuous (a) and data (b) sequence.
Mr Chase justifies the idea and perhaps tries to reconcile it to a younger culture by saying, "Having a radio-transmitting chip under your skin makes you very unique".
Transmitting data between chips by placing a transmitter next to a receiver, along the lines of the Sun design, employs an effect known as "capacitive coupling" to send electrical pulses at high speed.
The MC-CDMA system divides the available bandwidth into a large number of narrow subchannels [6 8] and spreads each data symbol in the frequency domain by transmitting all the chips of a spread symbol at the same time, but in different orthogonal subchannels.
Before the race, each runner's chip is assigned a unique seven-character code, which the chip transmits through a weak radio signal picked up by a technology called radio frequency identification (or RFID) each time the runner crosses a magnetic field, triggering the squealing sound that has become the system's signature.
The hackers are storing the data transmitted via the chip, thus enabling them to reuse the card data to clone both the chip and the magnetic strip.
The chip transmits a nine-digit number that tells Mr. Smith which snake he is tracking.
