Description
Technical Field
The invention relates to the field of wireless communication, in particular to a system for judging carrier modulation priority in wireless communication.
Background
In communication technology, a carrier wave is an electrical wave generated by an oscillator and transmitted over a communication channel, modulated to carry voice or other information. The carrier frequency is usually higher than the frequency of the input signal, which is a high frequency signal that is modulated onto a high frequency carrier as if it were riding a train of high-speed rails or an airplane, and then transmitted and received. A carrier wave is the physical basis and vehicle upon which information (voice and data) is conveyed.
The unmodulated periodic oscillating signal is referred to as a carrier wave, which may be a sine wave or a non-sine wave (e.g., a periodic pulse train), and the carrier wave is modulated and referred to as a modulated signal, which contains the full-wave characteristics of the modulated signal. The frequency of the sinusoidal carrier is generally required to be much higher than the bandwidth of the modulated signal, otherwise aliasing occurs and the transmitted signal is distorted.
The channel is a logical concept, is a channel for users to transmit information, and is artificially defined. In FDMA, a channel is a radio wave of a specific frequency, and each user uses a pair of frequencies to carry information when receiving/transmitting information. In order to increase the frequency utilization and increase the user capacity, 2G starts to adopt TDMA. A channel in TDMA is a fraction of the time on a radio wave at a particular frequency. The unit of a channel in a TDMA system is a composite unit that describes both the frequency (Hz) at which the channel is located and the time at which the channel is located, and the carrier is a continuous signal operating at a single predefined frequency. Changing the carrier so that it can represent the data in a format suitable for transmission is modulation, as we often say.
At present, in end-to-end wireless communication, carrier modulation in different channels is modulated according to a sequence and then transmitted to terminal equipment, but basic data information of different terminal equipment access channels is different, so that the capacity of receiving signals is different.
