While these examples have concentrated on the GSM system, this technique of calculating the phase and frequency error is applicable to most of the digitally encoded modulation schemes that rely on a relative change in phase to convey a bit pattern. The entire process of sampling a burst, calculating its phase trajectory, demodulating, producing a perfect trajectory, and calculating frequency error, peak, and RMS phase error, can be carried out using high-speed digital signal processors in a second or less (Figure 19.3c). 19.4 Interference Generation Tests Spurious emissions tests are designed to protect other radio spectrum users from unwanted emissions from transmitter or receiver circuitry in mobiles or base stations. Specifications vary for mobiles on a call or in idle mode, and for different cellular systems. Depending on the design of the mobile, conducted and radiated spurious emissions must be checked. Testing spurious output over a variety of extreme power supply and temperature conditions sometimes can be revealing. When a mobile s battery voltage droops, the circuitry should switch off cleanly, rather than getting stuck in an unpredictable mode with unwanted RF outputs. Spurious emissions tests can be made conveniently using a spectrum analyzer (Figure 19.4). The resolution bandwidth and sweep frequency range are chosen for the particular cellular system and type of spurious signal that are being checked. In

the actual size of the dish, with its diameter being about 10 times its wavelength of interest for high gain, low loss, and extreme directivity. Figure 10.24 displays the helical antenna, which is constructed of a nonconducting center strut helically wrapped with wire or tubing. This type of antenna is circularly polarized, so the opposing antenna of the system must be wound with the same sense, or little or no reception is possible. While the helical is a simple and low-cost antenna to design and build, its gain and beam width do not compare favorably to those of the dish antenna.

The following statement assigns a value to jagged[0][1,0]:

4. Solve the system of equations above for the coef cients Aj. 5. Using the methods below, evaluate the B-splines or B-spline derivatives as needed to determine displacement, velocity, acceleration, jerk, and other elements between constraints. Evaluation of B-Splines and Their Derivatives. B-splines can be evaluated by means of a well-known recurrence relation (Cox, 1972; deBoor, 1972). This relationship for the case here, in terms of the cam angle, x, and given the knot sequence, T, is N j ,k ( x ) = x - Tj Tj + k -1 - Tj N j ,k -1 ( x ) + Tj + k - x Tj + k - Tj +1 N j +1,k -1 ( x ) (5.7)
