The paper consiaers construction 01 wireless systems with flexible architecture based on the 802.11 standards. Advantages of such approach are reviewed. Theoretical analysis, laboratory tests and field trials of communication backbone line for system with flexible architecture are performed.
Principles of signal-code sequence (SCS) are examined. New methods and technical solutions are proposed to select the type of signal structures in order to achieve the best throughput and performance in wireless communication channel. The information efficiency criterion for channel resources usage is proposed based on the analysis of indicators and criteria that are recommended in the standard 802...
The algorithm of choice an optimal combination of multiposition keying and antinoise code is proposed in this paper. The criterion for selecting the optimal combination is the maximal productivity in base station coverage area of mobile communication.
The signal-code sequence (SCS) synthesis method for OFDM (orthogonal frequency division multiplexing) subcarriers is presented for achievement the required bit error rate (BER) on the receiver side in the channel with permanent parameters. The method is proposed as an alternative against the single carrier (SC) transmission and for achievement the required BER.
