Capacity in Wideband Code Multiple Access (WCDMA) systems is interference limited, it is also strongly linked with coverage. The greater the level of influx of users within the cell, the higher the interference and hence the lower the cell coverage becomes and vice versa. This is called Cell Breathing. In this paper a Walsh coding is used as a precoding stage to the Multiple-Input Multiple Output-Orthogonal...
As a result of increasing international air traffic, airports are one of the most complicated built environments. Airport terminals will increasingly require ubiquitous systems with high levels of computational power to provide the necessary intelligent automation, high quality services to passengers and stringent levels of safety and security that are as unobtrusive as possible. These requirements...
Peak-to-average power ratio (PAPR) is a major drawback in most multi-carrier communication techniques such as orthogonal frequency division multiplex system (OFDM). OFDM consists of lots of independent modulated subcarriers, as a result the amplitude of such a signal can have very large values. These large peaks increase the amount of intermodulation distortion resulting in an increase in the error...
In third generation (3G) wireless systems we have a number of resources being used exclusively and simultaneously to satisfy the requirements of an arriving multimedia call. This would require the occupation and release of these resources to be in a manageable fashion. In this paper, we discuss a multi-component teleservice model for multimedia applications. Subsequently, based on this teleservice...
