LTE_WCDMA_GSM Global System for Mobile Communications: Originally developed as a pan-European standard for digital mobile telephony, GSM has become the world’s most widely used mobile system.

Four measurement setup configured to demodulate LTE, W-CDMA Code Division Multiple Access: One of several digital wireless transmission methods in which signals are encoded using a specific pseudo-random sequence, or code, to define a communication channel. A receiver, knowing the code, can use it to decode the received signal in the presence of other signals in the channel. This is one of several "spread spectrum" techniques, which allows multiple users to share the same radio frequency spectrum by assigning each active user an unique code. CDMA offers improved spectral efficiency over analog transmission in that it allows for greater frequency reuse. Other characteristics of CDMA systems reduce dropped calls, increase battery life and offer more secure transmission.

This is a pulsed, standard PDC Personal or Pacific Digital Cellular: A Japanese standard for digital mobile telephony in the 800 MHz and 1500 MHz bands. To avoid the previous problem of lack of compatibility between the differing types of earlier analog mobile phones in Japan (i.e. NTT type and US developed TACS type), digital mobile phones have been standardized under PDC. In the case of the PDC standard, primarily six channel TDMA (Time Division Multiple Access) technology is applied. PDC, however, is a standard unique to Japan which renders such phone units incompatible with devices which adopt the more worldwide prevalent GSM standard. Nevertheless, digitalization under the standard enables ever smaller and lighter mobile phones which in turn has spurred market expansion. As a result, over 93% of all mobile phones in Japan are now digital. format signal.

5 MHz pulsed carrier with two TDMA Time Division Multiple Access: A technology for digital transmission of radio signals between, for example, a mobile telephone and a radio base station. In TDMA, the frequency band is split into a number of channels which in turn are stacked into short time units so that several calls can share a single channel without interfering with one another. Networks using TDMA assign 6 timeslots for each frequency channel. TDMA is also the name of a digital technology based on the IS-136 standard. TDMA is the current designation for what was formerly known as D-AMPS. (time division multiple access) bursts. Both bursts are QPSK modulated at 50 ksymbols/second, and are root raised cosine filtered with an alpha of 0.35.
