Maximizing Channel Capacity Of Crowded Spectrum Using Advanced Modulation And Coding Techniques
ABSTRACT
In this work, the relative
spectral efficiency of modulation and coding schemes in a bid to assess their
frequency maximization capacity is analyzed and studied using the Bit Error
Rate (BER) performance index. This performance index was obtained experimentally
with the use of Simulink BERToolbox in Matlab 7.5 and practically with BER
measurements from an existing GSM link using Ericsson BER performance software.
Experimental results showed that Quadrature Amplitude Modulation (QAM) and
convolutional codes had 35% and 44% performance improvement at the expense of
26% and 31% spectral efficiency respectively. The real life BER performance of
the communication link between a Mobile Switching Centre and a Base Station
Controller was observed to be 0.02. These results led to the conclusion that
QAM and Convolutional coding schemes proffer the best tradeoff between
performance and bandwidth maximization
