The performance of a CDMA based wireless system is largely dependent on the characteristics of pseudo-random spreading codes. The spreading codes should be carefully chosen to ensure highest possible peak value of auto-correlation function and lower correlation peaks (side-lobes) at non-zero time-shifts. Simultaneously, zero cross-correlation value at all(More)
Code Division Multiple Access (CDMA) is the predominant multiple access technology for future generation wireless systems. The performance of CDMA based wireless systems is largely based on the characteristics of user specific spreading codes. The objective of this paper is to highlight the various factors affecting the choice of these spreading codes and(More)
— OFDM may be combined with multiple antennas at both the access point and mobile terminal to increase diversity gain and/or enhance system capacity on a time-varying multipath fading channel, resulting in a multiple-input multiple-output (MIMO) OFDM system. This paper discusses the basic introduction to a general MIMO-OFDM system including the block(More)
Multicarrier CDMA is being proposed as a predominant candidate for future generation wireless mobile communication. One of the major drawbacks of a CDMA system coupled with multicarrier modulation is high value of PAPR due to multicarrier transmission. This PAPR can be effectively controlled through proper selection of a spreading code. The objective of(More)
Synchronization technology is an indispensable tool in wireless communication. The probability of missing synchronization and false synchronization is a good metric to evaluate the performance of synchronization. In this paper, we utilize some new classes of ideal punctured binary sequence pairs and compare their synchronization performance with known(More)
