But, the main difference between the two is that network coding requires encoding operations at intermediate nodes while traditional source coding only encodes packets at the source node.
Note that mutually correlated source signals arise from encoding operations on the bit stream including channel coding, modulation, and space-time coding at a transmitter [7, 32].
In the first time slot, the source node multiplies the signal vector ( mathbf {x} in mathbb {C}^{Mtimes 1} ) by a source precoding matrix ( mathbf {B} in mathbb {C}^{M times M}.) Here, the signal x contains mutually correlated data symbols with covariance matrix E(x x H )=R x =Ψ x known to the three terminals since x has been arisen from encoding operations on the baseband signals [7].
The benefit from millisecond and submillisecond simultaneity of stimulus pulses may reflect encoding operations taking place at the earliest stages of visual processing, i.e., in the retina.
It is not clear, however, whether activity associated with recollection for a particular source detail (i.e., encoding operations, spatial location, color) also varies according to the nature of the stimulus content at study or test.
This effect is more evident if the memory trace is laid down through deep encoding operations involving the recruitment of specific neural networks.

In order to reduce the difficulty of alignment for encoding operation between inter-communication traffic, the width of OFDM subcarrier pulse is stretched in our proposed scheme.
In [20], Qian et al. vacated room after encryption with a distributed source encoding operation, which can avoid to pre-process original image before encryption and has a high capacity.
In this example, the cube mapping [ 26] by the encoding operation [ 27] identified of the corners of a 2D plane as being 'a' → [0, 0], 'c' → [0, 1], 'g' → [1, 0], 't' → [1, 1].
Furthermore, the tolerance of misalignment existing in inter-ONUs traffic is investigated and analyzed for all-optical encoding operation, and the difficulty of pulse alignment is proved to be lower.
Figure 4 shows an example of original and encrypted video before the encoding operation.
