What is VSWR (Voltage Standing Wave Ratio) and How tilting antenna

What is VSWR (Voltage Standing Wave Ratio) and How tilting antenna VSWR means voltage standing wave ratio which everyone knows but why it comes to calculate in Telecom? When BTS transmit any signal (LTE, CDMA, GSM, WCDMA anyone) then in radio wave transmit through cable and reach to antenna so what? Now I give you … Read more

OFDM implementation in Detail

A typical OFDM transmitter is shown on the following figure. To reduce the amount of RF hardware required for OFDM the modulation process is split into two parts. A first part uses the inverse discrete Fourier transform (IDFT) or one of its more efficient but equivalent implementations known as Inverse Fast Fourier Transform to modulate … Read more

Capacity and MPR and CINR Distributions for LTE

Throughput or bandwidth that LTE was taken for the physical layer for the MCS under the pick or sustainable conditions. Throughput, individual users might be depends both on the MCS allocated (a function of characteristics and conditions of the user channel) and the requirements of other users sharing the channel resources (as arbitration Scheduler). Similarly, … Read more
