Multi-access communication system
A multiple access slotted wireless communication system comprising a plurality of terminals and a multi-access receiver is described. The multi-access receiver can decode multiple transmissions in each slot of a frame from terminals in its field of view. Each terminal has an active state for transmitting and an inactive state. After receiving acknowledgement of a successful transmission by the terminal, the terminal enters the inactive state for at least a transmission delay time. This may be the remaining time that the terminal is in the field of view of the multi-access receiver. This may be achieved by the terminal using a probability of transmission to determine whether or not to transmit in the next frame. The terminal may also be configured to select the slot in a frame, and this may be based upon information such as which slots were acknowledged. The receiver may use compression to transmit acknowledgement messages.
Communication system, terminal, and control method
In a communication system that includes an access point, a repeater #1, and a repeater #2 and wirelessly communicates with a terminal, the access point wirelessly communicates with the repeater #1 on at least a first channel included in a first frequency band and wirelessly communicates with the repeater #2 on at least a second channel included in a second frequency band different than the first frequency band, the repeater #1 wirelessly communicates with the terminal on at least a third channel included in the second frequency band, and the repeater #2 wirelessly communicates with the terminal on at least a fourth channel included in the first frequency band.
Optical transmission system and carrier monitoring apparatus
An optical transmission system includes: first and second optical transmitting units for respectively transmitting first and second optical signals that are obtained, respectively, as a result of first and second frequency-multiplexed multi-channel signals being converted by means of FM batch conversion; a carrier monitoring function unit for monitoring each carrier signal included in the optical signals; an output adjustment unit for adjusting signal intensities of the optical signals and outputting the optical signals; a multiplexer for outputting a multiplexed signal of the optical signals; an amplifier for amplifying the multiplexed signal; and first and second optical receiving units for receiving the respective optical signals included in the amplified multiplexed signal. The output adjustment unit adjusts the respective signal intensities of the optical signals such that the signal intensity at each optical receiving unit is larger than or equal to a predetermined value. The carrier monitoring function unit updates the predetermined values based on a minimum optical sensitivity that is calculated based on the amount of frequency deviation of each carrier signal included in the optical signals.
