The running time of quicksort can be improved in practice by taking advantage of the fast running time of insertion sort when its input is “nearly” sorted. When quicksort is called on a subarray with fewer than k elements, let it simply return without sorting the subarray. After the top-level call to quicksort returns, run insertion sort on the entire array to finish the sorting process.

These codes require an ASCII input file called input.dat of the following form: Lower Limit on x Upper Limit on x Final Time Pressure for x<0 when t=0 Density for x<0 when t=0 Speed for x<0 when t=0 Pressure for x>0 when t=0 Density for x>0 when t=0 Speed for x>0 when t=0 These codes produce 8 ASCII output files: density.out. Density vs. x entropy.out. Entropy vs. x mach.out. Mach number vs. x massflux.out. Mass flux vs. x pressure.out. Pressure vs. x sound.out. Speed-of-sound vs. x velocity.out. Velocity vs. x waves.out. A description of the solution in terms of the three waves defined in the book (+,-,0).

The book you’re holding, physically or electronically, is the result of a very interesting, challenging but also rewarding research project. The research was carried out in different contexts and cooperations but it was centered around the following question: how can we make the RF transmitters of our modern com- munication systems (WiFi, GSM, LTE, and so on) more flexible and more efficient at the same time.

Driven by the desire to boost the quality of service of wireless systems closer to that afforded by wireline systems, space-time processing for multiple-input multiple-output (MIMO) wireless communications research has drawn remarkable interest in recent years. Excit- ing theoretical advances, complemented by rapid transition of research results to industry products and services, have created a vibrant and growing area that is already established by all counts. This offers a good opportunity to reflect on key developments in the area during the past decade and also outline emerging trends.

Wireless communications has become a field of enormous scientific and economic interest. Recent success stories include 2G and 3G cellular voice and data services (e.g., GSM and UMTS), wireless local area networks (WiFi/IEEE 802.11x), wireless broadband access (WiMAX/IEEE 802.16x), and digital broadcast systems (DVB, DAB, DRM). On the physical layer side, traditional designs typically assume that the radio channel remains constant for the duration of a data block. However, researchers and system designers are increasingly shifting their attention to channels that may vary within a block. In addition to time dispersion caused by multipath propagation, these rapidly time-varying channels feature frequency dispersion resulting from the Doppler effect. They are, thus, often referred to as being “doubly dispersive.”
