SYSTEM PARAMETERS

Number of primary radios:
Number of quantization levels of the ADCs (Re and Im):
Dynamic range of the ADCs (Re and Im):
ADC overdrive factor:
Lenght of the impulse reponse of the low-pass receive filter at the CR:
Vector with the impulse response of the receive filter (default: moving average filter, hi = 1):
IMPULSIVE NOISE PARAMETERS
Number of impulsive noise (IN) bursts during one sensing period (default: 1)
Number of samples per IN burst (default: 20% of n):
Ratio betwen impulsive and thermal noise powers (K = 0 for zero IN):
Probability of occurrence of IN during a sensing period:
Average fraction of CRs hit by IN:
SIMULATION PARAMETERS
Number of runs in the Monte Carlo simulation:
Detection technique:
Options:
"ED" (Energy Detection), "ERD" (Eigenvalue Ratio Detection), "RLRT" (Roy's Largest Root Test), "GLRT" (Generalized Likelihood Ratio Test). The last three are adequate for p = 1.
Primary transmitted signal:
Options:
"Noise" (X have filtered noise samples, depending on the RX filter lenght, L).
"BPSKiid" (X have filtered BPSK samples, depending on the RX filter lenght, L).
System model to be analyzed:
Options:
"C" (conventional model)
"R" (realistic, implementation-oriented model)
Impulsive noise countermeasure:
Options:
"M" (mute samples above +-D/2 when IN is present).
"E" (eliminate from cooperation those CRs under IN).
"N" (no IN-specific countermeasure at all).
Auxiliary routine for the r
Auxiliary routine for the permutation matrix for vector rotation
Auxiliary routine for computing the average number of CRs in cooperation for the IN coutermeasure "E":
