Bit error simulation of FSK, BPSK, and pi/4 DQPSK in flat and frequency-selective fading mobile radio channels using two-ray and measurement- based impulse response models
… performance of digital mobile radio systems in fading channels. The simulation tool generates average bit error rate (BER) and bit-by-bit error patterns with user-specified parameters. The simulation tool can simulate various communication system parameters (i.e. modulation scheme, data rate, …

Hybrid Orthogonal Code Sequences for High-Density Synchronous CDMA Systems
… to ensure accommodation of large number of users and to minimise the effect of multiple access interference. In this research, the design for a novel hybrid orthogonal very large set (HOVLS) code sequence is proposed for high density mobile application scenarios. The design and development of both …

The Impact of Channel Estimation Error on Space-Time Block and Trellis Codes in Flat and Frequency Selective Channels
… researchers as a means to improve the energy and spectral efficiency of wireless systems. Among many classes of schemes, Space-Time Block codes (STBC) and Space-Time Trellis codes (STTC) have been the subject of many investigations. Both techniques provide a means for combatting the effects of …
