Web• Excellent Receiver Sensitivity: Processing for Improved Sync Detect – –123 dBm at 1.2 kbps Performance – –109 dBm at 50 kbps – Security: Hardware AES128 Accelerator ... WebSpectral efficiency, spectrum efficiency or bandwidth efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently a limited frequency spectrum is utilized by the physical layer protocol, and sometimes by the medium access control (the channel access protocol).

It is shown that a GMSK receiver consisting of two matched filters and a four-state Viterbi algorithm performs with less than 0.24 dB degradation com- pared with the optimal receiver. The linear receiver is optimum for all values of E,/& (bit energy to noise one-sided spectral density ratio).
