To allow a mobile station to make communication with a base station of a micro cell usually and to make communication with the base station of a macro cell when the mobile station is moved at a high speed in a mobile communication system where macro cells and micro cells are in co-existen...
The application of unslotted ALOHA to mobile communication systems is studied. In such systems, the terminal-to-base channel can undergo various types of fade such as shadowing (log-normal fading) or unshadowed multipath reflections with a direct component (Rician fading), or the near/far effect...
The paper addresses Rayleigh fading, primarily in the UHF band, that affects mobile systems such as cellular and personal communication systems (PCS). The paper itemizes the fundamental fading manifestations and types of degradation. Two types of fading, large-scale and small-scale, are described....

Communication system with concatenated coding error correction In the concatenated coding data compensation communication system, the coding and decoding are performed in a differential coder and a differential decoder. 2-channel output obtained after coding is parallel- to-serial converted and then... ...

From this distribution one could determine, for example, how reliable the communication link is for a random location within the indoor space. If each simulation contains 5,000 bits, 100 simulations would process half a million bits in total. This is substantially fewer bits compared to the ...
For combating the fast Rayleigh fading usually encountered in mobile communication channels, convolutional coding and Viterbi decoding together with interleaving and the BPSK system using an orthogonal sounding tone are considered. The bit error probability performance of the system is analysed, and numeric...
In mobile radio communication, the fading channels generally exhibit both time-selectivity and frequency-selectivity. Orthogonal frequency division multiplexing (OFDM) has been proposed to combat the frequency-selectivity, but its performance is also affected by the time-selectivity. We investigate how var...
摘要: Presents information on a study which proposed a pilot symbol-assisted modulation to overcome the Rayleigh fading compensation in land mobile communication. Description of the fading compensation method using fast Fourier transform; Bit-error rate performance in Rayleigh channel; Conclusions....
