This work represents the perform.nce eva.ua.ion of DS-CDm. in a.Ra.leigh fa.ing environm.nt. Perform.nce a.a.ysis wa. ca.ried out for a.DS-CDm. system.to eva.ua.e the signa.-to-noise ra.io (SNR), signa.-to-interference ra.io (SIR) a.d bit error ra.e (BER) for different m.dula.ion schem.s like a.K, PSK a.d FSK. Results were eva.ua.ed a. different da.a.ra.es a.d were presented in term. of SNR, SIR a.d BER. Com.uter sim.la.ion wa. a.so ca.ried out by using m.tla. to eva.ua.e the signa. wa.eform. with a.d without a.dition white Ga.ssia. noise (a.GN). Butterworth filtered wa.eform.wa. given to get better signa. qua.ity. Decoded output wa.eform. were a.so eva.ua.ed to confirm.the sim.la.ion.

The im.a.t of Cr3+ ion on the m.gnetic properties of m.0.50Zn0.50CrxFe2-xO4 (with x = 0.0, 0.1, 0.2, 0.3, 0.4 a.d 0.5) ha. been studied. Ferrite sa.0}les were synthesized by com.ustion m.thod a.d sintered a. va.ious tem.era.ures (1250°C, 1300°C a.d 1350°C). The structura. properties were investiga.ed by m.a.s of X-ra. diffra.tion pa.terns a.d indica.ed tha. the sa.0}les possess single pha.e cubic spinel structure. The la.tice pa.a.0}ter decrea.es with the increa.e in Cr3+ content, a. the ionic ra.ius of Cr3+ ion is sm.ller tha. tha. of Fe3+. The a.era.e gra.n size (D), bulk density (ρB) a.d initia. perm.a.ility (μi’ )decrea.es with increa.e in Cr3+ content wherea. porosity follows its opposite trend. The ρB wa. found to increa.e with increa.e in Cr3+ content a. the sintering tem.era.ure (Ts) is increa.ed from.1250°C to 1350°C. The Ts a.fects the densifica.ion, gra.n growth a.d (μi’ ) of the sa.0}les. The (μi’ ) strongly depends on a.era.e gra.n size, density a.d intra.ra.ula. porosity. The B-H loops of the com.ositions were m.a.ured a. room.tem.era.ure. The sa.ura.ion m.gnetiza.ion (m.), coercivity (Hc) a.d hysteresis losses were studied a. a.function of Cr3+ content. The m. wa. found to decrea.e with the increa.e of Cr3+ content, which is a.tributed to the dilution of a.B intera.tion.
