Why bpsk modulation technique is used in gps receiver?
Two main reasons: 1) The frequent phase inversions induced by a simple PRN waveform allow the receiver to calculate precise ranging. BSPK also easily facilitates the use of the Gold Code in PRN sequencing, allowing the SVs to broadcast on t... Read More »

What modulation technique used in mobile phones?
Currently the mobiles use GSM(Geo Synchronous Mobiles ) and CDMA(Code Division Multiple Accesss) techniques. GSM inturn uses TDMA(Time Division Multiplexing) or FDMA(Frequency Division Multiplexing) or sometimes both to fit in the required ... Read More »

CDMA uses a special type of digital modulation called spread spectrum which spreads the voice data over a very wide channel in pseudorandom fashion. The receiver undoes the randomization to collect the bits together and produce the sound. G...

hi, given the non linear response of the channel, modulations which carry information mainly on the phase of a carrier signal are preferred. thos include qpsk, 8psk, bps, CPM, GMSK, etc. Also, under certain conditions, that is, ensuring tha...
