Embodiment
[0122] Embodiment: In the vehicle network communication system, it is assumed that there are 20 users and 10 sub-channels in total, i represents the user number, and n represents the sub-channel number. The 10 channels are randomly assigned to 20 users, ensuring that each user is assigned at least one sub-channel. For a sub-channel, the signal transmitted in the channel is the superposition of all signals transmitted in the sub-channel. Therefore, the signal transmitted in subchannel n where p i,n Indicates the transmission power of the i-th user's signal in sub-channel n, if user i does not occupy sub-channel n, then p i,n =0. the s i Denotes the symbol delivered to user i.
[0123] At the receiving end of the IoV communication system, the received signal for any user k on sub-channel n is:
[0124]
[0125] where h k,n is the product of the Rayleigh channel gain and the path loss between the base station and the user, z k,n is mean 0, variance is additive white...
