37.203 is an application field and a working principle that is used in the field of mobile telecommunications. It applies the principle of Orthogonal Frequency Division Multiplexing (OFDM) for transmission. OFDM is a type of multiplexing scheme that divides the available frequency spectrum into many narrowband sub-carriers. These sub-carriers are then modulated individually to create a data stream. OFDM has several advantages over other multiplexing schemes, such as being able to support higher data throughputs, higher coding gains, and higher resilience to multipath distortion.

The stated application of 37.203 is within 3GPP (Third Generation Partnership Project), a worldwide collaboration of telecommunications associations. The application allows for the transmission of higher data rates using the Orthogonal Frequency Division Multiplexing (OFDM) scheme. The application aims to enable a higher level of quality of service through the implementation of higher Orders of Modulation (OM).

In terms of the working principle of 37.203, it involves the dividing of the total available spectrum, denoted by the maximum frequency fm, into many sub-carriers. These sub-carriers are then modulated separately with different orders of modulation so that they can carry the desired data rates. The modulation used must be orthogonal in order to avoid interference between the sub-carriers.

Once these sub-carriers have been modulated, they are combined to form a signal that contains the accumulated data streamed from all the sub-carriers. This signal is then transmitted over the air using an antenna. Upon reception, the received signal is decomposed back into its individual sub-carriers and the data is processed accordingly. The data is then output from the receiver after being decoded.

The application of 37.203 enables a higher level of throughput and greater resilience to interference due to its utilization of the Orthogonal Frequency Division Multiplexing (OFDM) scheme. This is achieved by using multiple sub-carriers that are modulated separately and then combined to form a signal, which is transmitted over the air using an antenna. The signal is then decomposed back into its individual sub-carriers, and the data is processed upon reception.

The working principle, as discussed earlier in this article, brings many advantages, as it can offer higher data throughputs, higher coding gains, and higher resilience to multipath distortion. Furthermore, 37.203 is also applicable in other wireless communication applications such as Multiple-Input Multiple-Output (MIMO) systems, which are used in many of the latest standards, such as the 4G LTE and 5G NR standards.

In conclusion, the 37.203 application field and its working principle offer many advantages that make them suitable for many mobile telecommunication applications. The Orthogonal Frequency Division Multiplexing (OFDM) scheme utilized by 37.203 allows for higher data throughputs, higher coding gains, and higher resilience to multipath distortion. As such, their application in 3GPP as well as in wireless communication systems such as MIMO systems is invaluable.
