An information stream with a bit rate R = 160 kbit/s is transmitetd by means of a digital modulation technique. a. Determine the number of data bits that is transmitted per channel symbol in case T DQPSK is used as modulation 4 technique. The number of bits/symbol = Number bits. - BT = Number kHz. T b. Determine the required null-to-null bandwidth Bī of the transmitted signal in case the same modulation technique & DQPSK is applied and rectangular channel symbols are used. BI Number kHz. fa n = Number bits/sec/Hz. c. Calculate the transmission bandwidth Bī of modulation technique QPSK in case a pre-modulation filter with a raised- cosine roll-off characteristic is applied with 0.75 and fo determine the spectral efficiency n for this modulation n scheme and used pulse shape. =
