MehrfachTrägerSysteme

MehrfachTrägerSysteme, often abbreviated as MTS, refers to a class of wireless communication systems designed to transmit data over multiple carrier frequencies simultaneously. This technique contrasts with traditional single-carrier systems where data is sent on a single frequency band. By dividing the total data stream into smaller portions and transmitting each portion on a separate carrier, MTS offers several advantages.

One of the primary benefits of MTS is its resilience to frequency-selective fading. In wireless environments, different frequencies can experience varying degrees of signal degradation due to multipath propagation. By using multiple carriers, a system can ensure that even if some carriers are severely affected by fading, others remain relatively clear, allowing for continued data transmission. This leads to improved overall system reliability and throughput.

Another significant advantage of MTS is its ability to achieve high data rates. By aggregating the bandwidth of multiple carriers, the system can support a much larger total bandwidth than a single carrier of equivalent spectral efficiency. This makes MTS well-suited for applications requiring high-speed data transfer, such as broadband internet access and high-definition video streaming.

Popular examples of MehrfachTrägerSysteme include Orthogonal Frequency-Division Multiplexing (OFDM) and its variants. OFDM is widely adopted in modern wireless standards like Wi-Fi (802.11a/g/n/ac/ax), 4G LTE, and 5G NR. These systems utilize a large number of closely spaced orthogonal subcarriers to transmit data efficiently. The orthogonality ensures that the subcarriers do not interfere with each other, simplifying the receiver design. The development and deployment of MTS have been instrumental in the evolution of wireless communication, enabling faster speeds and more robust connections.
