How can you send several separate signals over a single baseband cable?

Using baseband transmissions, it is possible to transmit multiple signals on a single cable by using a process known as multiplexing. Baseband uses Time-Division Multiplexing (TDM), which divides a single channel into time slots.

How is baseband signal generated?

In telecommunications and signal processing, baseband is the range of frequencies occupied by a signal that has not been modulated to higher frequencies. Baseband signals typically originate from transducers, converting some other variable into an electrical signal.

How many bits can be transmitted in each time slot with baseband transmission?

The maximum number of transport blocks within a TTI is 96 and the maximum number of bits that can be received within a 10 ms radio frame interval is 57600. In this section we explain and discuss the baseband functions (shown in Figure 4) with focus on the downlink data channel processing in the RBS.

Why can't baseband signal not transmitted directly?

But a baseband signal cannot be transmitted over a radio link or a satellite because this would require a large antenna to radiate the low-frequency spectrum of the signal. Hence the baseband signal spectrum must be shifted to a higher frequency by modulating a carrier with the baseband signal.
