Time dispersion is another problem relating to multiple paths to the RX antenna of either MS or BTS.Time dispersion causes inter symbol interference where consecutive symbols (bits)interfere with each other making it difficult for the receiver, which bits is correct one
When turning on the SINCGARS (Single Channel Ground and Airborne Radio System), you should set the channel switch to the "MAN" position. This allows for manual entry of the desired frequency or channel. After setting it to "MAN," you can then enter the appropriate channel or frequency for communication.
The modulation used in GSM is Guassian minimum-shift keying (GMSK), a kind of continuous-phase frequency shift keying. In GMSK, the signal to be modulated onto the carrier is first smoothed with a Guassian low-pass filter prior to being fed to a frequency modulator, which greatly reduces the interference to neighboring channels (adjacent channel interference).

The "ch" in "temp" most likely stands for "channel," where it refers to the designated channel or frequency used for transmitting and receiving data or signals in a communication system or device.
To calculate the system parameters of Orthogonal Frequency Division Multiplexing (OFDM) systems, you typically start by determining the bandwidth and subcarrier spacing, which are influenced by the number of subcarriers (N) and the total bandwidth (B). The subcarrier spacing can be calculated as Δf = B/N. Additionally, the symbol duration (T) is the inverse of the subcarrier spacing (T = 1/Δf), and the total duration of the OFDM symbol, including the cyclic prefix, is crucial for mitigating inter-symbol interference. Finally, the signal-to-noise ratio (SNR) can be assessed based on the modulation scheme and the channel conditions to optimize performance.
RF channels are specific frequencies within the radio frequency spectrum that are used to transmit data or signals wirelessly. In the context of television, RF channels are used to broadcast TV signals over the airwaves to be picked up by antennas. Each RF channel corresponds to a specific frequency for transmitting and receiving data.
There are two processes:- 1 Bandlimited channel 2 Multipath propogation
Channel estimation in Orthogonal Frequency Division Multiplexing (OFDM) refers to the process of estimating the characteristics of the communication channel through which the OFDM signals are transmitted. This estimation is crucial for accurately recovering the transmitted data, as it allows the receiver to compensate for the effects of multipath fading and frequency-selective fading inherent in wireless channels. Techniques such as pilot symbols and training sequences are often used to aid in the estimation process. Accurate channel estimation helps improve the overall performance and reliability of the OFDM system.
The geometrical parameters of a channel typically include its width, depth, slope, and cross-sectional shape (such as rectangular, trapezoidal, or circular). Additionally, the channel's length, side slopes, and bank height may also be considered. These parameters influence flow dynamics, sediment transport, and overall hydraulic behavior within the channel. Properly defining these parameters is essential for effective channel design and management.
The spread spectrum technique is supposed to be less susceptible to natural noise, co-channel RF interference, intentional jamming, and unauthorized eavesdropping. It should also be less susceptible to degradation due to multipath fading, which is highly frequency-selective.
