RECEIVER SENSITIVITY Clause Samples
The Receiver Sensitivity clause defines the minimum signal strength level at which a receiver device can reliably detect and process incoming signals. In practical terms, this clause sets a technical threshold, often measured in decibels-milliwatts (dBm), that the receiver must meet or exceed to ensure proper operation within a communication system. By establishing this standard, the clause ensures that equipment is capable of functioning effectively in its intended environment, thereby reducing the risk of communication failures due to inadequate signal reception.
RECEIVER SENSITIVITY. Receiver sensitivity shall be compliant with PN3383, (Draft American National Standard or Telecommunications - Recommended Minimum Performance Requirement for Base Stations Supporting 1.8 to 2.0 GHz Code Division Multiple Access (CDMA) Personal Stations) with the following clarification / exceptions. Baud rate = 14.4 kbps Item 2 in section 3.4.1.2 Method of Measurements should be amended to read
RECEIVER SENSITIVITY. The typical received input RF power (measured at the antenna output port) to achieve a decoded [***] shall be as shown in the table below. The receiver sensitivity for a decoded BER of [***] is nominally [***] dB higher than for [***].

RECEIVER SENSITIVITY. Base Station receiver sensitivity shall be measured at the Base Station site equipment level. Antenna, connector or cable losses are not included as part of this measurement. Mast mount or external Low Noise Amplifier (LNA) equipment shall not be included as part of, or included with, this measurement. Lightning suppression devices which contribute loss to these systems will be included if this suppression device is located at or with the Base Station site equipment. Mast mount or coax line feed installed suppression devices will be included in the antenna / coax feed loss budget. Sensitivity measurements shall include any internal cell sites equipment internal (e.g., LNA, frequency selective components such as band pass or band reject filters, and receiver path signal).

RECEIVER SENSITIVITY. Receiver sensitivity is defined as the RF power at the antenna output in the receiver. For each modulation and coding scheme, receiver is expected to process the signal properly when the incoming signal power is greater than the threshold. Table 1 shows the receiver sensitivity for each modulation and coding scheme. Higher modulation requires higher receiver sensitivity, because higher modulation requires a better SNR. Figure 15 shows a measured signal-to-noise and distortion ratio (SNDR) of received signal with various received power. The gray line describes the required SNDR for each MCSs. For example, at −61 dB, which is receiver sensitivity of MCS 0, required SNDR for stable transfer is about 5.7 dB. As seen in Figure 15, current TS2 chip achieves better SNDR compared with the requirements and also see some improvements from previous version of chip, TS1. In this test, the SNDR is obtained by measuring single tone RF signal. So actual SNR of modulated signal will be degraded due to phase noise or RF impairments.
